Wait, are you Richard, or did someone named Richard send that to you?
I am doing Cranksgiving also (did it last year, too). The fun ride is also doubling as Cycle Memphis's November ride. CM usually rides the first Saturday of the month starting at the corner of Cooper & Young in Midtown.

I also try to roll with the Breakaway Running Cycling Group on Sunday afternoons. They usually do a slower-paced ride cuz I'm slow
