No serious physical considerations, I could have made it with no trouble but my friend is 11 years older than my 44 and has almost convinced himself that hes getting old. Besides it gave use an excuse for a camping trip when there was so much work my buddies wife thought we needed to be doing, and instead of making her mad she felt sorry for us. I have also added a new kit to my truck it's smaller than my full kit and it's small enough that I have no excuse for not having it with me anywhere I go from now on.
