I was at the Bucks county rally and was about 20th in line. (Forgot to reset the car clock for EST so was an hour earlier than early.)
They had about 20 metal detectors manned by TSA that were ready to go at 2 but didn't open 'til near 3. There was still a line at 6 or thereabouts so many just stood outside the fence where they could see and hear the action from a distance.
IMHO, get there 2 hrs. before the official gate open time and have an empty bladder.
Thank you!!!
