My family and I just got back from a great float trip on the Gulkana trip. The only problem is, on our way home my raft started to deflate on my trailer. It's really weird. When I got home I blew it back up, washed it, and sprayed it with soapy water. I can not find a leak anywhere. I know it didn't deflate from a simple temperature/pressure change, because the floor was still completely inflated. I checked the valves and seams. It seems to be holding air in my backyard right now. I am going to check it again in the morning to see if it holds air. Any ideas? I am completely baffled.
