From Barnes, I would do an out and back with my gear to Pine Mountain via Dolly Copp Road.
Again I am not sure how far I would actually make sense it might not be broken out. The main thing is to get out and test my gear at low temps and a hike is a hike, even if I am on a Forest Service Road.
I need to call the USFS and find out if the Barnes and Hancock are plowed. I may end up shoveling for exercise rather than hiking
What did you think of Acadia in Feb or March ?
