Rhino at rest

While walking around the San Antonio Zoo, we came across the rhino enclosure.  I think rhinos are interesting - they seem somewhat prehistoric to me.  Anyways, this guy was just standing there when we first arrived, and I tried to get some shots but nothing was too exciting.  Anyways, he meandered about for a short while and then plopped down for a nap.  I was able to walk to the other side of his enclosure to get this shot.  Zoom in a little and presto!  Doesn't it seem like zoo animals are always napping?  I guess they get bored just like we would if we were cooped up forever.  One day I would love to visit Africa and get some shots of real wildlife, doing whatever they do in the wild - probably napping!
