I did 3 of the 4 cat 3 stages last year. It was alright. Organization was fine last year. Payouts were a little slow (like an hour and a half after the race) for those of us who needed to drive home, but otherwise no complaints about how it was run.
The GC is weird -- it's time based, but all the road stages are flat, meaning a pack finish is likely. So the GC is basically just the TT standings. I heard that the last stage, held after the TT, was fairly active with a break getting away, but that was the stage I missed.
We had 70+ person fields in the cat 3s. Mostly Ohio and Pennsylvania racers it seemed.
Worth doing, but no a Tour de Toona.
