From A Separate Peace:

“His enlistment seemed just another of Leper’s vagaries, such as the time he slept on top of Mount Katahdin in Maine where each morning the sun first strikes United States Territory. On that morning, satisfying one of his urges to participate in nature, Leper Lepellier waas the first thing the rising sun struck in the United States.”

I want to do this this summer. Yep.
