I live across the lake from DFW National.  I also manage an oil change/repair shop in Grand Prairie near I-20 not far from DFW National.  PGR Riders are welcome to stop for a restroom break, air for tires, or to road check their rides.  If this is useful, I will provide the location and hours.  Not trying to pitch my business, all we really do on bikes is State Inspections.
