it is not just an air bladder,it is interconnected pockets.
physical therapist know about the material for bed ridden patients.
Then I headed over to where my girlfriend works. Greg, the boss, followed us outside and kept trying to tell me about how he went to Las Vegas one time on a motocycle. I was like, "oh-kay, that's great Greg."
Just back from Prudhoe Bay, IMO it was really worth the trip, AK is a beautiful place & you need lots of time to take it all in. I'm looking forward to returning & exploring some places i didn't have time to ride.RIP Ron Melton
