Im planning on doing a thru hike starting early-mid August. My tent weighs about 2.5 pounds, and since my other gear is also somewhat heavy, I was wondering if I could skip using a tent in the northern section. I plan on carrying it at least to Middlebury Gap, but once the terrain starts to get harder, losing the weight will help a lot. [Im very skinny so every pound counts] Would it be stupid to rely on shelters north of Middlebury Gap, or on any part of the trail?
