great time - educational, good value, fun
Kathy (the owner) was a great tour guide. She didn't operate off of a boring generic script, but interacted with the group. Waited for questions, was flexible with the timing; while ring respectful of everyone's plans. The flow was great and there were few hills that we really went up; interesting feat in San Fran. :-). Thanks Kathy, i wish u continued success with your business.
