Palermo, Maine Speed Traps

Was going back to Boston from Acadia Nat. Pk when I received a ticket. Route 3 is one lane in each direction with a few uphill sections that have a slow lane for trucks. I came upon one of those sections and when in merges back to one lane at the top of the hill over the crest was a maroon Impala set up for shooting laser at the top of the hill. I was pulled over by a Crown Vic that came out of the woods as was a fellow motorist by a second Crown Vic. All cars were unmarked, though that isn’t a factor in this particular set-up.
