Ah, Maine in the December. The perfect time to visit: no mosquitoes, no tourists, no bears. And, as it happens, no Acadia National Park. When I went with two of my friends, we found the place closed and deserted; park access roads were blockaded with snow, and the lights were off at the visitors center. Fortunately, the trails weren't blocked off, and we were still able to have a good, albeit freezing, time.
