The best thing about Mexico City!!!! Closing down a huge route to cars, for people to enjoy on…read moretheir bikes, rollerblades, and feet. They have a lot of police and volunteers making sure that the traffic flows smoothly. I´ve ridden my bike a few times, but I prefer to take the opportunity to get in a long run. There are also yoga and Zumba-esque classes that happen near the Angel and Glorieta monuments. Families, couples, tourists, everyone is there to get in some exercise outdoors and it is really fun. I go every Sunday, and it is still the coolest thing I´ve seen.
