We're doing a 20 mile circuit in Aug and I was looking into trying to cut my backpack weight down and considered leaving the waders and wet wading.
We chose to take ours with. The temps are actually a bit cooler then I expected and will be even a bit cooler since we will be starting at 8,000 feet and working our way up into the 11,000 range.
Besides breathables with boots only weights about 3 pounds.
We have been working with 2 Rivers in Pinedale and they have been real helpful. Had them send me a selection of drys, streamers and nymphs to copy for our trip. Terrestrials (sic) seem to be the ticket.
Spoke to a friend up there. Though he does not flyfish he fishes stick baits with alot of success.
You don't have alot of time left for planning, but "Walking the Winds" by Rebecca Woods was a pretty helpful source of info.
If you have time please follow up with a thread when you get back. We are hitting Pindale on Aug 17th, through the 25th. If there is any info you could pass along to help us with our trip we would appreciate it.
Good luck and be safe..............................I have been told seveal times while researching this that it's Grizzly country.
