Most people within the middle to higher classes tend to be part of the "Bicycle Sundays", when the local government shuts down major throughways to motor vehicle traffic, giving the right of way to thousands of cyclists.Other popular activities include going to one of the three city zoos, the aquarium, or spending the day at any of the large parks found within the city, such as Chapultepec, Aragon, Parque Lincoln or the Alameda Central.
