I had 10 firm commitments, and 3 other maybes,  for the ride I had put together for Sunday.  When all was said and done we had 3 fat bikes, 3 cross bikes and 1 29er.  We had 2:30 – 3:00 of easy rolling on tap, but the cold conditions, and the block head wind made us wish we had went into the woods instead of the paths and parks.  When all was said and done we had 1 flat, 1 messed up cassette, 1 mud bog tractor pull, and 1 failed attempt at clearing a sand firm.  Not too bad for cold December ride.
