You decide to keep walking in the same general direction. If Dexter lost his keys, maybe he dropped something else that could help you out of this situation. Or like, a Pedialyte. You pocket the keys and see if you can spot anything ahead. Sure enough, about 20 feet away are what look like beer bottles, stacked like in a carnival game. Its a little further away from the road, but you feel like you're on to something so you walk over.

There are 6 bottles of Miller light, set up in a pyramid. They look like they've been sitting there a while- there are more than a few flies buzzing around. This is weird, but you also don't see anything useful or interesting. Dexter probably just got drunk with his friends in the clearing by the side of the road and wanted to throw rocks at something. Sure enough, the neck of the top bottle is broken off.

There's nothing pointing you in any direction. You're about to go back to the road when you spot a yellowed piece of paper rolled up inside the broken bottle.
