"Not much longer..." Sam said, although he was a little unsure. He'd been following the markers, pieces of string tied to regular trees, that he'd set when they built the trehouse, but he hadn't used it of about a year. Following the markers was easy enough, except he hadn't seen one for a while now, and was wondering if they'd gone wrong.
"I think we should go back a little bit, just to that last piece of string..." he suggested.
