The are two traps on the southbound side of Interstate 81. The first one is about halfway between exits 170 and 168. They have a dirt pull off on the left side behind some brush. They can’t get the northbound side because of guardrail. Also they sit about a mile down the road just past the bridge going over Exit 168 on the left side behind the dirt pile. Speed Limit is only 55 and a saftey corridor so you fine will be doubled.
