definitely and get directions or even better a gps track and go for a longer loop to tam. Roaring mouse near the base of the golden gate on the sf side has demos--->Gallery :: Demo BikesGet a red Golden Gate trail map, ride across the bridge and explore one day. There is some fun stuff between the bridge and Muir Beach.
Right, I forgot that $1 charge. It is for a technical reason for their liability insurance or something like that. Pretty much free though.technically, they charge your card $1. but yeah, outside of commute hours it's like 1:30 each way to SC. if you can swing that, you should line up a demo from HQ.
I was going to say this. If you would like to go riding with me send me a PM. I should be free next week. Should be.sunshine in fairfax has some nice ibis demos; from there you can ride from the shop to tamarancho (redwoods! downhill flow trail!), and there's more stuff too nearby. also closer to SF than any of the options on this thread except skeggs, where there's no services of any kind. (you can probably rent a decent bike in sf and go to tamarancho and skeggs and ride in the city itself at sutro.)
