Weez-
You asked about the condition of the trail. When I hiked the JMT, I marveled at the spectacular views that unraveled themselves at every step. Not so on the LT, it is more like hiking in a green tunnel. When I commented on the lack of views to a fellow thru-hiker, he objected and pointed out the great variety of views on the LT: roots, roots around rocks, rocks near roots, rocks and roots covered in moss, rocks and roots hidden under wet leaves, rocks and roots peaking up out of the mud, rocks and roots hidden beneath overgrown nettles… it goes on. The LT is rooty and rocky, but still well worth the trip.
I hiked both the LT and the JMT in Julys ('05 and '06), the LT has lots of rocks and roots, and the trail doesn’t switchback very much, but doesn’t have the snowpack I ran into on the JMT, or the river crossings. And while their are bugs on the LT, I’ve never seen mosquitos like those I encountered on the JMT.
Happy Hiking
