First, as birdny pointed out well over a year ago, the links need to be updated for Michaux State Forest.
Second, a clarification on the "Getting There" directions from Gettysburg and I-81. From the 233/30 junction, drive 4.15 miles south on 233/ Rocky Mountain Road. At the "T" intersection, do not continue to follow 233; turn left and drive towards (and past) the South Mountain Restoration Center (signed). 1.7 miles after the "T" intersection, turn right on Old Forge road. The Appalachian Trail crossing will be in 3.4 miles. There is room for parking for less than 10 cars in three different pullouts, but it doesn't seem to be an issue.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
