Pearl and the campers are still asleep, so you've got a few precious minutes to yourself. Maybe you can do some investigation!
You've already discovered that the reception out here is The Worst. You can barely get two bars on a good day. (It's one of the big selling points for parents; you've seen that in the brochures. "Get your kids away from their screens and into nature at Camp Cedarcrest!" "Surf the waves, not the web!" Not that there are waves on the lake, but still.)
You'll have to use what little time, phone battery, and data you have very wisely. You might be able to do some research on that person living in the woods, but you won't have much time to do it. And it will be hard, too; you don't have a name, just a location and some ideas. Maybe you could research that real estate deal instead: Capewide Developers, and what they want with Camp Cedarcrest.
Or you could ask someone back home to do the research for you. And when it comes to research, "someone" usually means "Haley." That would get you a lot more information. But there's no way of telling how long it will take to get it.
Or you could just use the time to talk to someone.
