I-81, Exit 54, South bound on ramp.
The on ramp is at the bottom of a hill, the Deputy or State Police or both sit on the left side of the on ramp, out of site from the south bound I-81 traffic that they radiate from behind as they pass the bottom of the on ramp. It is such a cash cow site that the highway department has put out gravel for the patrol cars to park on. I got a ticket here and received solicitation from three different lawyers in Marion wanting to represent me. I made my $128 contribution to the slush fund and tried to forget it. But I always go slow down the south bound Exit 54 hill. Also about a mile south from exit 54 is a rest area with a big area in the median paved, better watch out there too.
