I try to do one tour per year, this year I picked the Tour Da UP hosted by the League of Michigan Bicyclists. I'm an experienced tourer (supported tours only). Anyone done this route and what can you tell about it (terrain, support, fellow cyclists, etc, typical weather). Reasons why I chose it include the fact it's a loop tour, which is far more convenient, group size limited to 150, and the daily mileage is reasonable. I was looking at the DALMAC tours, but some of those days were just too long.
