On April 22, a few days after watching the Golf Channel documentary “Arnie,” Adam, 21, a keen golfer himself, wrote a letter to Palmer on behalf of his younger brother Nate, asking if he “could possibly write Nate a letter wishing him good luck in college and providing him some advice along the way.”
He could not have known that he would get so prompt a response from a man who receives thousands of requests annually, eventually responding to all of them. The letter he sent to Nate was dated May 23, one month later.
