This was something on my bucket list for a while and I'm glad we were able to fit it in. It was just the two of us with our guide, Dain, and he stopped often to give us the background and history of what we were seeing.
It was very easy to learn, and I did not feel unsafe on the roads at all (and we're in our mid-60s). Dain was a great guide, and took pictures at numerous stops along the way. The Segways definitely attract attention.
