I'm hiking northbound, Monson to Katahdin solo in the end of August. What is the best/cheapest way (college student on a budget) to get back down to my car in Monson once I pop out in Baxter. I'd prefer not to get a shuttle service, as the cheapest one I've found so far is $100. Has anyone had any luck hitching back? If not what do you all reccomend?
