Haha, just saw this and I live a little further than a mile, more like 7
Darlington is somewhat picky on Saturdays for test and tune (like only allow slicks) mainly due to their bracket racing going on that day as well. However, possibly in March 09, the bracket season won't be started yet, and they'll allow street tires at the test and tune (like all of their scheduled test and tunes).
