Armadillo with JD and his son, 12 years old at the time. Was told by Kathadin rangers we couldn't go up to Chimney Pond in the evening (we had been to the plane crash site earlier in the day, so we were getting a later start than hoped for) "the mountain is closed" so we got a late (5 am) start. Spent too much time short-roping the kid up the approach slabs, had to wait out a T-storm 3 pitches below the top, took the Cathedral trail down, which was slow due to darkness, steeps and taking care of the kid. 23 hours car to car. Poor kid was bushed.
