As DH and I were saying last night... aren't Segways just taller
ECV's? It's unfortunate when those who have disabilities have to miss out, but in this case... why not just let the other wheeled vehicles join the group? But to have to build a special Segway just for this tour? **.
And this isn't a ride... it's a tour! I once went on a Walking Tour of Europe, and the tour said it was mainly long days of walking, and we had a few in the group who couldn't keep up. If they had a Segway or an ECV, it sure would have made a difference!
