In the summer of 2005, I hope to finish my hike from Harpers Ferry to Katahdin. Are there any major sections where hammock hanging is either too difficult, or impossible? For example...can you get through the white mountains with a speer type hammock? I would be leaving Harpers Ferry, or the 1/2 way point in Penn (if I can hike this spring break). I also should have a long summer this year...toward the end of August, beginning last day of May. One more quick question, I've heard that the Northern AT is more difficult than the southern AT. Is an 84 day hike from the 1/2 way point to Katahdin feasible?
