My populaire will be the Bobcat Bite 103 k, starting in Celina, a little bit North of Prosper.  We will start at the same time, 08:45 Sunday, October 27.  It's listed in ridewithgps.com three times.  I will check the route out later this week, but this route has been done more recently than the RBM one.
 
Get there from the Dallas area by going North on US75, the Dallas North Tollway, or I35E.  From Fort Worth, use I35W.  The I35s go to Denton.  Go East from there on US380 to Prosper.  The Tollway sort of stops at 380, and Prosper is a bit East of there.  On 75, take 380 West.  At Prosper, take 289 North (where the overpass is) 8 or 9 miles to Celina, and bear left onto Business 289 (Oklahoma Dr.), or turn left further on at FM455.  Go up to Pecan St. (455) and turn left, three blocks to the town square.  Park on the East side of the square.  Parking is also available on nearby streets.

The populaire is still on starting from Celina at 08:45.  The route is from Steve Petty, with cosmetic updates (eliminated a couple of phantom turns, updated names of controls).  I expect the rain to be gone and maybe even some sunshine.  Lots of East-West travel will mitigate any wind.  Did I mention FM455 has been resurfaced?  With smooth macadam?
