our 8th grade classes in my jr high went to Gettysburg every year. The best part of the trip was Devil's Den.

the year before we went, my friend Pat fell from the top of those rocks and broke his fucking head open. right on his left eye. he broke the orbital bone and was lucky to not lose his left eye. he still has the scar.
the next year, my class went....we were NOT allowed to climb on those rocks.
