The A Bar A ranch is where I caught my first trout when I was a kid. Great place!! As for rivers to float I would recommend the Snake and the South Fork of the Snake as well as the Upper Green. You should give a shout when you get out here. Maybe we can hook up for some fishing while your here.
Don't know if your interested or not but I still have my old boat. It is a 90 16ft Lavro outfitters dory. I'm looking to unload it for 2500.00. Thats trailer boat oars anchor and spare tire included
