I was visiting my husband who is working in SF and we anted to try a bike tour. he saw this one on Trip Advisor and thought it looked good--well, it was better than good it was truly WONDERFUL. John, our guide, was patient, knowledgeable, and funny, and then some. Traveling through difefrent types of neighborhoods to get a sense of the cultural heritage of the city was a highpoint, but going through parks and visiting a yummy chocolate store were also great. To top it off John was happy to give many recommendations and spen asmuch or as littel time fielding questions and sharing stories. We will be reccommending this to everyone who has some time for a ride in SF. Thank you, John!!
