I am so used to riding with my husband, so if my tube or C02 fails he can go get the car and fetch me, or vice versa. I am now in cape cod on my own for 3 weeks. I've been going out with 4 tubes (I ride a terry so I need 2 diff. tire sizes, 2 tubes per size), a patch kit, and a topeak road morph pump (heavy but gets me over 100 psi) instead of my usual 2 tubes and C02. I was feeling ridiculous until I read your message, but the last thing I need is to be 30 miles from my cottage with no one to come get me! Its great you found folks to help, but self-sufficiency is always best.
