I need to go back and measure an ATV trail in central Maine. We were headed south so went down it but I wonder how people go up it at all. The trail joins a state highway for a short distance to cross over I-95. While still high on the overpass embankment, the trail takes a hard right through a gap in the guardrail and down the rocky embankment. It was OK going down, but going up would require enough momentum to get up the loose rocks. Then there's about 2 meters from the top of the hill to the traffic lane of a fast straight stretch of state highway.
