Cheetah Aid DC, a group that advocates for cheetahs, had an event a couple of weeks ago at the Park Triangle apartments, the building on the Civic Plaza with the first floor retail. Apparently they had a live cheetah on the roof of the place. Pretty crazy!
There have been some random animals in the neighborhood, like at Columbia Heights Day's petting zoo, which had a camel.
Flickr user alex.DC, who took this photo, also wrote about the event on his blog. Sounds wild, a cheetah on a leash! He has a couple more shots on his Flickr too.
