Very Nice! You live in a beautiful area of the world. I was there last fall for Oktoberfest, although I must confess that I do not do well with crowds and was happy to get out to the country after a few days.
In New Hampshire, they do not title vehicles over 15 years, so older than that you get an annual registration. I was able to get an 'antique title' for my old Norton and BMW motorcycles when I moved up here, but am not sure if they still offer them. As an antique though, you can skip one year between inspections. NH does still require safety inspections on all vehicles, no emissions yet. I am still restoring my Chrysler, so haven't had time to really experience it.
ein schöner Tag,
Erich
