In PA. I pulled over for a minute and when pulling back out got stuck on a curb. I was going to walk home for the night so I took my pint of whisky and walked a half mile up the road drinking the whole way. Then turning around I saw an ambulance at my car. So, I sat and thought about it, drank some more and walked back drinking along the way. Then I put my almost empty bottle and keys by a tree. I told the people there it would have to be towed. Along came the State Police and gave me a DUI. Should I fight it? What are my chances?
