There are 2 parts of this trap one is as soon as you past Girard road off of Doyle the lines are set about 50ft apart (3 of them) and Whitehall police sit in driveways of houses either on the left or the right which ever there prefer. Have seen them on both sides of the road. The other part of the trap is as soon as you past the stop sign at frich drive you go down a hill and marked cars sit on the right of the road either in driveways or bushes. They enforce it heavily at night so you cant see them at all, as they are undiscoverable with there lights off at night. The speed limit is posted at 35 and its very easy to go over that and not pay attention going down a hill. 35 are no more they don’t give you a break.
