Back around 1985 or 86 I was on my way to the game lands on rt 501, a two lane state road, in Lancaster Co. north of Lititz heading north. I was driving down a long steep hill obviously a no passing zone. All of a sudden I saw a car passing me at a high rate of speed, he passed me and about 8 other cars, I estimated his sped to be close to 100 mph. There was a light ahead about a 8th of a mile and there was a school bus stopped discharging students at that light. This idiot never slowed down and went around the school bus in the oncoming traffic lane on the other side of the light. Kids scattered everywhere and fortunately none got hit. As soon as the bus started to move and turned left and I cleared the light, I ht my reds and the siren and took off after the moron. When I got to the next light at the intersection of state rt 322 I saw traffic was stalled, then I saw the vehicle I was after parked in the middle of the north bound lane just beyond the intersection. People pulled over and left me go around them and I got the the guys car I saw he was passed out behind the wheel. I opened his door and woke him up and it was obvious he was stoned on something, I smelled no weed. I pushed him over and moved his car off the road in to a parking of a stop and rob and tried to question him. He was too far in outer space to have a conversation with I took his car keys and got his information, registration etc and radioed for a state trooper. I had the school bus number so I called the school and told them what happened and asked for the bus driver to contact me. She did and she had not thought to get the license plate number of the vehicle so I was glad I did. I told PSP I would be happy to testify gave them my contact number and waited. No one ever got back to me to testify so I have no idea what happened. We were not allowed to enforce traffic violations at that time so I had done all I could do but in my mind it wasn't enough. There are some very stupid people on the road and our illustrious governor wants to legalize MJ so there will be more under the influence drivers to contend with.
