among my group of friends, certain gear will get shared. With caveats- as in, totally the gear owners perogative to share or not.
We are white water boaters too, and we have several close firend that we have a cash/crash policy with... we all borrow big expensive gear back and forth, with the total understanding that if it gets damaged, it gets replaced. Mark wasn't too happy when he snapped the tongue off our trailer, but he took care of it.
I never understand when people borrow stuff and don't take responsibility for it.
As for bikes, it's nice to know who has spares for when buddies come into town. ;-)
