To either of the 2 original posters here, our group (2 cats and 4 people) is launching on the Main Salmon, July 11th. We won't have much room in terms of being able to carry other folks gear, but we're all pretty laid back and enjoy like minded folks. We figure the more goof balls at camp the better.
We don't drink on the river, we might drink a bit at camp. We'll be stopping to see the highlights along the way, will probably scout the bigger rapids.
We'll be leaving from Boise on the 10th, and there is room for additional boats on my trailer, but no room in my vehicle for additional people. We're paying to have my vehicle shuttled to Carey. You're more than welcome to carry on to Spring Bar if you want.
Let me know if you're interested - and at the very least it sounds like we'll be seeing one of you at the put-in!
