I am planning a solo driving trip (June or July) through New Hampshire, Vermont, and Maine for either the summer of 2013 or 2014. (Alter I visit these three states, I will have seen all 50 states, and all but Hawaii by driving!) I am primarily interested in natural scenic areas, historic sites, old churches, and wildlife. Most nights I will be camping, but may also stay in budget B&Bs or local inns. My plan is to have at least 3 days in Vermont. I will be driving from Alabama, so my route will most likely be south-to-north or west-to-east. What are some "must-sees" in Vermont?
