Looks like we'll be swinging through Idaho and Wyoming in late July but I've never been fishing up there so could do with some suggestions? What should I be looking to take with me? I'll have limited room, so probably only one setup. Thinking I'll take my 4 wt and I guess waders if need be, not sure if I need them at that time of the year? Any other suggestions of where to go and what to take will be mucho appreciated.
