Joseph Priestley (1733-1804) was known for identifying carbon monoxide, but mainly as the…read morediscoverer of oxygen in 1774. He was also a theologian, educator, political activist and writer. He spent the last years of his life in then rural Northumberland, Pennsylvania. He was a strong supported of the political ideas of the french revolution and had supported many religious Dissenters (both no-no's in his homeland of England), for this his house, library & laboratory were burned down, he was accused of treason and then he immigrated to The United States. First settling in Philadelphia, then moving to northumberland, he had hoped that moving to such a rural and secluded area would perhaps give him some breathing-space and time to think. He wasn't welcome as a preacher in Northumberland, but founded the first congregation of Unitarian faith in Philadelphia. His house was equipped with a laboratory, where he conducted experiments. His ideas greatly influenced Thomas Jefferson and the Constitution, and also his education planning is the basis for the liberal arts college. This is basically a tour of his original house, it has been modified since then. takes about a half-hour. 4.00 admission per person.

Dan pretty much hits the nail on the head in his review. I'd heard of the Joseph Priestley House…read morebefore, but I'd never visited it. Not only did Priestley discover oxygen, he also conducted early experiments in electricity and counted Benjamin Franklin, Thomas Jefferson, and James Watt among his friends. His teachings were so controversial that his house in Birmingham England was burned to the ground. He and his family fled Engand and Priestley spent the last decade of his life in Northumberland. The Joseph Priestley House is a National Historic Landmark and from the outside, it looks like a typically unassuming English gentleman's estate. But it's really easy to spend some time in here. Priestley and his family not only lived here, he had his laboratory here too. And I'm happy to say that the lab has been recently renovated. When the lab was renovated, it was done so without intruding on the elements of the house. The exhibit is set as though Priestley is at work investigating carbon monoxide in his Northumberland laboratory. Reproduction glassware pieces were selected, based on pieces that Joseph Priestley was known to have used here. The original laboratory glassware is now at the Smithsonian Museum in Washington, DC. Other renovations include two representative furnaces with chimneys and a fume hood spanning the width of the lab. There's also a lot of family history in the house. His spouse Mary Priestley did a lot of the planning for the new house. She passed away, however, two years after they arrived in Northumberland and she never saw the completion of the house. As a widower, Joseph Priestley lived here with his eldest son, Joesph Priestley Jr and his daughter-in-law and his grandchildren. In 1919 Dr. George Gilbert Pond bought the house at auction. Dr. Pond was dean of the School of Natural Sciences at Pennsylvania State College (now Penn State). After his death in 1926, the college purchased the house and built the Pond House in his honor. It was used as a firepoof museum for Joseph Priestley's artificats. It once served as a visitor center, however plans are afoot to adapt it for public meetings and exhibits. I think that visiting small historical houses such as Priestley's can be just as rewarding as visiting well-known museums. If you visit the Priestley House, do the "Priestley Pilgrimage" by also visitng the Joseph Priestley Memorial Chapel, Riverview Cemetery and Northumberland's Historic District.

Located in Centre County, PA (which apparently has over 130 caves!), this unique tour takes you through a beautiful limestone cavern entirely by boat. The cave tour lasts about 45 minutes and costs $25 per person. They also offer a wildlife tour by bus, but we only had time for the cave portion. Be aware there's a fairly large staircase you'll need to go down to reach the cave entrance. Something to keep in mind if anyone in your group has mobility issues. Each boat holds around 22 people, but we visited on a quiet Monday afternoon and only had 8 in our group, which made it feel more personal. Our tour guide was excellent and knowledgeable, engaging, and had a sense of humor. He encouraged questions and had thoughtful answers for everything we threw at him. At the end of the cave, you actually exit into a small lake, take a brief spin around, and then head back through the cave to where you started, very cool and peaceful. There's also a gift shop on-site that sells snacks, drinks, and the usual souvenirs. Tours typically depart every 30 to 60 minutes depending on how busy they are, so timing is pretty flexible. All in all, it's a fun, unique experience that's well worth the stop!

You really can learn a lot about someone by seeing the place they chose to call home. Getting there is part of the adventure--you enter via a long, single-lane gravel road. It's so long you might wonder if you've made a wrong turn! Thankfully, GPS got us there without trouble. When you arrive, there's one long row of parking spaces. Head straight to the ticket area for your house tour pass, as they do seem to run out early. While you wait for your tour time, you can explore the expansive outdoor areas. Our favorites were: 1. Eisenhower's vehicles, including the limo that shuttled him to and from Washington, D.C., every weekend. 2. The Secret Service room with the small safe that once held the nuclear codes. 3. The putting green, where we enjoyed a little golf while taking in the gorgeous countryside views. 4. The greenhouse and patio, where we imagined the President and Mamie spending peaceful afternoons. We were lucky to get tickets for the 11 a.m. tour, which began with a 10-20 minute ranger talk about how the Eisenhowers chose this home and some of the people who lived and visited here. Tip: arrive a little early--the ranger shared some great informal stories before the official tour began right at 11 a.m. Inside, the ranger spent about 5 minutes pointing out key details, then let us explore at our own pace with a pamphlet to guide us. Indoor highlights included: 1. The portraits of President Eisenhower, Mamie, and their son John. 2. The TV in the informal living room--such a relatable touch for a world leader. 3. The special staircase wallpaper Mamie ordered, featuring the seals of all 50 states. 4. Mamie's very pink bedroom and bathroom. Between the history, the personal touches, and the beautiful setting, this is an absolute must-visit in Gettysburg.
