I will be departing central Maine (Bangor area) on August 16 with my brother to drive to Portland, OR. We plan to spend about 12 days on the trip, we will be camping every night, and we would prefer to avoid interstates. I've been looking at routes, and I can't decide between taking route 2 or 20. We're interested in seeing the best of the northern US, particularly quirky towns and beautiful scenery. Have any of you done either of these routes? Neither of us can decide which would be better. Also, this will be our first big road trip, so any pointers would be helpful!
