If I were you would head south on I75 and not stop till I got to SGMP. It would be worth the extra time and fuel costs to tow there. Call the track tell them your coming and they will probably roll out the red carpet for you... It is the nicest facility I've been to south of the Mason/Dixon line. If it's testing time you are after I would recommend getting in on a track rental rather then tnt nite.

as for Rockingham, don't care if I ever go back there...
