Here are my two cents: the anticipation is worse than reality. The longer you postpone getting on the bike again, the more ominous the highway and trail will become. Just go out again, be careful crossing that highway, and have a ton of fun. Falling on the highway is an event with a very low probability. I am guessing you have crossed it hundreds of times before without a glitch.

That Spot device sure looks intriguing. Do you carry a RoadID on your wrist?
