It costs $65 for silver membership ... and probably less to call a cab.
Plus 9or miuns) there is This: "Flat Tire Assistance - If the bicycle is rendered immobile as the result of a flat tire, a service provider will be dispatched with commonly available tools upon request or have your bicycle transported. We do not deliver bicycle equipment (i.e. bicycle tires)."
So for $65 you will show up and tell me that it is a shame i got three flats and only carried two tubes? Sure. i can see no tires ... but tubes? patches? Tire boots? plus 80 percent of the bikes on the road have or can fit about one of five tire sizes ....
I am sure there are otehr benefits to joining though ... but Triple A seems like a better investment.
