But when you put little kids on a narrow path with parents that don't really care, cute things sometimes happen... not that I condone it. Regardless, while waiting for Old Faithful, I came across a cluster of people standing like a clot on the sidewalk. They were watching a little girl giving a chipmunk random objects, like blades of grass or nuts. The chipmunk was happy to receive and kept the crowd entertained for a few minutes before another kid jumped in to try the same feat, scaring the chipmunk away. I did my best to stay about 10 feet away from the action, but I couldn't resist a few shots.
