Bike Friendly Oak Cliff will be sponsoring the Dallas Santa Ride, 2:30 pm on December 20th in downtown Dallas. They will also be collecting toys for Toys For Tots. Costumes and decorated bikes are not required but highly encouraged. Definitely not for the "serious cyclist" these rides are relaxed, leisurely jaunts that almost always end with beer (or other beverage of choice)
