These guys were enthusiastic, friendly and helpful. As we waited for our tour to start, the guy behind the counter who checked us in (sorry, I have forgotten names!) asked us about ourselves and gave us some ideas for other things to do and great places to eat. Our tour guide was knowledgeable and when we unexpectedly got stuck in traffic during our electric car tour, he did a good job of continuing to engage us and the other people in the car, and made the trip fun. Definitely worth doing to get a good history overview of the city.
