I was just in San Francisco for work and wow, props to you girls for riding there. I don't know how you can handle those hills! A really steep downhill with a stop sign at the end, that would definitely take some time to get used to. Same with the uphills. Your legs must be bricks! Sadly, it was all work and no play, so I couldn't ride, didn't even get to visit a bike shop (I did peek in the window of one in palo alto though and saw a gorgeous bamboo frame).

San Francisco definitely puts Michigan riding to shame
