The Lamar River is a renowned fly fishing river and of course runs through the Lamar Valley. I came across this idyllic scene while driving around looking for grizzly bears (which unfortunately we didn't see.) The fisherman, river, golden hills and bison in the late day sun make this a classical view of what Yellowstone National Park is about. (Well, except for the lack of geysers, but you can't have everything. :) )

If you're into fly fishing, this image just might represent your idea of the dream vacation!
