Not that this was ME or anything, but a field I know of in SW GA was frequently the site of late-nite drag racing---the people involved would ensure they had a handheld tuned to the unicom just in case somebody came in late---but it was mostly a crop-dusting field, so traffic was pretty sparse. Again, not that it was ME or anything, but I knew a guy...!
BTW, the local cops, fire dept, etc all knew and as long as no FOD was left on the runways they didn't seem to care---I don't know what a rep from the FSDO would have thought...
