DH and I have given away 2 tubes and 2 CO2 bottles this season. One guy, we found walking his bike down the road, carrying his shoes (he didn't have cleat covers) in his bare feet. His feet were raw from walking on hot asphalt. When we gave him the tube and CO2, I thought he was going to cry with relief.
I definitely believe that this is guaranteed good tire karma! We are always well prepared, but never have flats on our bikes. Still, we've been able to help some other riders and that feels good.
