My husband and I began our S.F. trip with the "Invention Tour". Robin led us through different ares of the city and shared lots of historical and scientific facts along with some hands-on activities. We enjoyed this tour so much that we scheduled another Geology tour a few days later! "San Francisco Rocks" was our favorite. We got to explore another part of the city with Robin as our guide, pointing out geology we never would have found on our own. My husband who is a fourth grade science teacher plans to "borrow" some of Robin's fun activities. Robin is someone who is very knowledgable and really enjoys sharing that knowledge. She has a wonderful presentation that is engaging and fun. She asked us questions from the beginning of the tour that got us thinking. We really loved her lighthearted style and sense of humor. We would highly recommend any of her tours for a unique experience in San Francisco!
