Hey, if I could only be living in Virginia right now..
I could go there before you had to take the trouble to check it out, then you wouldn't even have to fool with it if it's not a good site. Ha ha.
On the serious side though, I ALWAYS use a low-powered, low-gain detector with low sensitivity in those places, taverns too. It seems to be a better way to go if there is crushed rock there.
Cancel the pulltabs and iron completely and dig anything above pulltabs. If you do you won't be pulling your hair out with all the noise and false signals and you'll be find a lot more silver coins and wheaties in a lot shorter time..
Wherever the toilets were, that's where to look first. Next I'd try the driver's side of the parking post. When you get through doing that, then use only foil and high iron to look for any silver rings or necklaces. I still to this day use that same technique and find the latter right after people run over the ground right ahead of me with some real spendy detectors.
