I've heard stories of busts out there, but none first hand. I was with Willis that night we saw that cop...he seemed to be occupied or just didn't see us. We both broke down trying to get out that night and had to wait 45 minutes for tow truck at one of the exits and never got hassled.
They had a lot of the ingress/egress areas barricaded last time I was out.
I think its just a trespassing ticket, but you know there's other contraband to worry about as well...
I'd say Willis is a little more cautious than I am, but I don't think I'd enter through the neighborhood/church as I imagine if a call is going in to PD, that's where it would originate.
Seems to me the cops would have to wait until you decided to come out, unless they mounted, which I have heard stories about as well
