Hey there! I went rafting several times with my pouch, and I had a great time. Load up on the immodium/lomotil and stick to your "low residue staples" that move your gut slowly (peanut butter sandwiches and bananas were always my outdoor adventure "go to"). Put some TP or wet wipes in your bag as well as some antibacterial hand gel. Make sure you hit the bathroom right before you leave, even if you don't have to go. Finally, don't let yourself worry about what would happen if you have to go in the woods. Most people will likely have to answer the "call of nature" at some point on a day trip, and a minute or two of waddling around in the forest is well worth a day of fun. Have a great trip!
