One might ask why Julien was hitting golf balls at camp, or why he even had a bag of clubs at a place where there were literally no golf holes. Blame the people who adorned the Nike cabin, because that's where he got them from - his cabin. Maybe it was because gold was considered an Olympic sport by the IOC, but those clubs had no use being at camp.
Or at least until Julien discovered them and invented his new favorite sport: Ares Golf. The rules were simple: hit balls until a landmine went off. And it was fun as hell to Julien. To the Nike demigod, it was always satisfying to see the Ares kids get all shocked when their days are disrupted by the loud BOOM outside their window. A bloody good time indeed.
But there would be no boom this time around, as the bal hit the ground and bounced into the opened doorway of the cabin. This made Julien very angry, so he set his tee back up and took another swing.
