All I know for sure is that I've loaned out my pump when asked. No biggie. I also have a patch kit and a small tool kit that I'd loan if the need arose.

Since I don't carry CO2, I don't loan that out, but probably would. (I guess you give that away, no?)

Why not? That's what makes a community work, the sharing of resources. If I loan out a pump it (in theory, at least) makes it more likely I'll get help if ever I need it. Right?

(going off to ponder philosophical issues...)
