After a regrettable bachelor party, a man wakes up in the desert with $45$ watermelons. He needs to get them across to an oasis $15$ miles away. He can only carry $15$ watermelons at a time, and he eats one watermelon every mile he walks, including walking back to where he started from. He can also leave watermelons at any mile he has walked, but no fractions of a mile. What is the maximum number of watermelons that he can take to the oasis?
