A few years back my wife and I toured Yellowstone before meeting my dad for a fly fishing boat trip.  It was a beautiful afternoon, warm and sunny, with the shadows just starting to appear.  The moon came over the horizon, and this guy looked up at me – a classic Yellowstone postcard.

There were a few other people around, and some who wanted to get way too close.  I was grateful when several other folks in the crowd gently (well, maybe not that gently) asked them to back away.  Let the wildlife be wild, and get a longer lens!
