The Wednesday morning Roll Call ride was thin, composed of myself and my friend Adam. I'm pretty sure the cold, foggy air had something to do with it. However, it didn't stop us. We had a great ride in the city, through the Presidio, Sea Cliff, a closed Great Highway and up to the top of Twin Peaks. There's a great climb to be had from the ocean all the way up to the peak. Almost a 1000' gain, but not quite. I never ride Twin Peaks, so it was a nice eye opener to the challenge just on the other side of hill I live on.
