OK - found this:
Mark said he tried texting Dylan all afternoon in an area with spotty cell phone service.
When he didn't hear anything back by late afternoon, he went to Dylan's friend's house in Vallecito. That friend hadn't seen him.
Mark became alarmed and drove the 20 miles to Bayfield. Dylan's friends there hadn't seen him either. Mark called Elaine Redwine and went to the Bayfield Marshal's Office.

The important thing to note is that it says: "That friend hadn't seen him". To me, that implies that perhaps that friend wasn't expecting him.
Otherwise, I would have expected MR to say that the friend said: "He never showed up". Not that any of this really matters. I'm just curious because even if they never talked (DR & Vallecito friend), who knows, depending on where that boy(s) lived, maybe DR took off on his own to just show up there to kill time. That's why I really wanted to know where that individual(s) lived, how far in relation to MR's home, and what was around the area!
Vallecito is really small, right? Is it the area of the town that is small, or just that there are not many people?
