I use Game Theory. No sane person would go on an extended sport climbing trip without a rope and a set of quickdraws. Thus, everybody you meet at, say, Ceuse, will have those things. Therefore, if a fella were to show up there with nothing but a pair of shoes and a harness, he should have no trouble finding partners with gear. On extended trips, when I hit Europe (and thus needed to camp at climbing areas), I'd spin the $12/day rental car past a Decathlon and pick up a $20 sleeping bag, $40 tent, and $1.99 giant inflatable pool toy mattress to serve as the envy of the entire campground. Everybody else has stoves and cookware, so that part's sorted. And when it comes time to fly home, some lucky dirtbag gets a bunch of free gear.
