Yes you and tdoczi have both pointed out correctly that for AT thru hikers heading north you can cross Route 4, continue on to Maine Junction and then keep heading north (really east at that point) and then drop down a short blue blaze trail to the Inn. For an LT north bound hiker that would be slightly more out of the way since we are heading north to Canada at Maine Junction.
I just thought the official Green Mountain Club position and how I learned of their position was slightly interesting. In my defense I do have this in the Long Trail forum. : )
By the way I really liked your original post in this thread. And it was interesting to hear why the relo was done in the first place from peakbagger.
My other thought is that perhaps long trails should provide two official trails in situations like this. Sure do the relo but say clearly either way counts. I think people would feel more free then to go the way they want rather then stay on the official trail so they don't later have to explain themselves as tdoczi references above "I hiked the LT, but . . ."
