sun review
This was an amazing trip for me. Idaho and the Salmon River are both absolutely spectacular - the people, the river, the food, everything was excellent. Your attention to details didn't go unnoticed. Thank you for a trip and experience that's at the top of my list of the best things I've ever done.
