I'd definitely ride with ACC again --- maybe even in Newfoundland, since I didn't get to see the Tablelands either time I pedalled past. I thought that it was brilliantly organized and run, but it took me a few days to learn to trust the system. But once I realized that I'd always have the information I needed by the time I needed it, I relaxed and enjoyed it.
Great trip! You haven't aged (much)!
Friendly people, good fun, spectacular scenery, sense of group togetherness.
Good variety with mix of long rides, short rides and off days. Got good value for the cost of the tour.
