Was curious if you were going to lead another Perimeter Ride this summer. If so, when?

If memory serves, today may have been the first time we've well met. I've long appreciated your contribution to the cause of bikes, anticipated meeting you, and was not disappointed.

Hello John, Will you be planning a Michael Jackson tribute ride? Or at least a little song?

Glad you could make it John - I think there should have been a prize for "sweetest ride" because you would have won.
