About a decade ago I was fishing the Gros Ventre in Wyoming near Jackson Hole and taking a fair amount of cutthroat on dry flies while working slowly down stream. I was "in the zone", as they say, when all of a sudden a big lady moose came crashing out of the brush and into the river. I was about a hundred feet upstream and almost jumped out of my waders. She stood and glowered at me and when it was apparent she wasn't going to move while I was around I went to the far bank and took the fisherman's trail upstream. When I got a ways away I looked back and she was nudging her small calf across the stream with her snout, a sight I'll never forget.
