Being on a tour with only 5 tourists in a van was so superior to the large bus options. Brian worked with National Geographic for more than a decade. He has studied the history of San Francisco, the architecture, and the various neighborhoods. I have been to San Francisco at least 1/2 dozen times, yet Brian showed us little known spots that I didn’t know about. He’s intelligent, has a great sense of humor and a refined presentation. He provided a nutritious snack of sourdough bread, special tortilla chips and organic almonds. There were restroom stops for those of us with small bladders.
