Gary was excellent as our bike tour guide. He is extremely knowledgeable about the city. Very impressive! He took us out for 3.5 hours, and we biked all over! The gardens and parks are amazing, and we stopped frequently to view the sites and learn about the history. I enjoyed the tour immensely, and would highly recommend! You don't have to be an excited on a bike, even with all tree hills! The bikes are very powerful, so not too much pedaling effort is required!! Very fun!
