I didn't know if geocaching was still a thing, because I never knew it was a thing! I am now "geocaching 101".
I'm wondering about LE doing another search. I know when they did the 12/8 search, this was reported:
The search is not prompted by any new leads in the case, according to the La Plata County Sheriff's Office. It is a common route between Durango and Vallecito, where Dylan was last seen. Investigators want to cover that area ahead of a possible snow fall that may hit the area Saturday night or Sunday.
Whether there was more to the search than that or not, we don't know (cell pings? something else?).
But there are clearly other places along the route from the airport back to the house (Sunday night) and from the house to ---> hitch-hiking route? (Monday morning). Unless there's snow on the ground or it's too frigid to search, why not organize another search to look for clues, especially if the first one was as random as LE insists it was.
