Great tour. Our guide, Juan, was very knowledgeable about the history of the sites in the downtown area and a pleasure to meet. Very good instructor on how to ride the Segue too. Delivered us at the Congress Avenue Bridge in perfect time to walk onto the bridge and see the bats swarm out.
It's on a Segway and although it's difficult at first, it's definitely worth it!
So much fun! My mom (66), my daughter(14) and I (47) went. Our guide gave good instructions and pointed out many interesting sights. A word of caution - much of the tour occurs on sidewalks with pedestrians who might unknowingly step out in front of you, causing a collision. No major damage tho! :)
