I think lots of people have tried to obtain a permit with no luck..
but like 1337 said, after 2am you should have no problems there.
and btw, you will probably only get a small fine, and it will not show up on any records, as long as you pay it. I was caught lost halloween, didnt show up to court, and they still dropped the charges. so chances are youll probably be ok if you get caught. But that being said, there are lots of ways to get into BG even when cops are patrolling the main road. And as long as its not October, I dont think you have to worry too much about cops being IN the grove either.
I would say just take the chance, and go for it.
