I found this in folder of older files. While visiting Washington DC back in 2012, I decided to take a walk around the Capitol and the Smithsonian area. It appears the squirrels there are very friendly. I think it’s a result of humans feeding them. This one actually followed me for several yards as I walked. It ran along the top of the fence; each time I stopped walking it stopped with me. The tiny creature let me take several photos before it scampered off.
The camera used at the time was Canon 7D with a Canon EF-S Zoom 15-85mm f/3.5-5.6 IS USM.
