When I found this tour on-line it stated an upper age limit of 70. I am over 70 so I emailed and asked about that restriction telling them that I had done this before and as recently as 6 months ago. They wrote back and said they would make an exception as long as I had no problem with the learing/control session before the tour. I did just fine and of we (wife and I) and three other people went. Great tour of the city with several stops (church, restaurant etc.).
