dmpaq20:Because I do it alone. Most everyone that I have met go on trips like this with either a spouse or as a group. I truly have a unique situation.
It's not that unique though. Family thing aside so many backpackers do what you do - and I'd do it in a second, because I know I'll always meet some great people. At times it's even nice to be technically rather than emotionally entangled with your buddy.
It seems to me you've got some unusual perks and not much of a choice, anyway ;0) - - which leaves me wondering like a few others here if some specific worry is causing you to look for reassurance?
As for buddies just be sure to check them out - especially if the dives' a little demanding, and they're bringing unwieldly extra gear like huge cameras - it's going to affect your sitation too. I've had a few weird ones.
