Re: Yellowstone or Wind River
I'm planning a similar trip to Wyoming for this summer. I think I'm going to go to the Wind River Range (though where specifically, I'm not entirely decided..it's a big place). Part of my own decision is that it'll mostly be a backpacking trip and I don't like crowds (not that the Yellowstone backcountry is crowded), but the other part of that is simply that there are a lot fewer grizzley bears in the Winds (none in the southern part of the range, as I understand it). Grizzleys kind of freak me out, to be honest...
I don't think August was a mistake, although the area around Jackson Hole can definitely get some routine afternoon thunderstorms almost every day, if that's what you're referring to.
Also, the previous poster makes a good point, "what are you looking to get out of this trip?" This would help us give you more relevant responses.
The other flies, n., pl.
1. dry flies, nymphs, emergers, terrestrials, streamers, etc.
2. What I use when a black #10 woolly bugger isn't catching.
