I don't think a young man who was pranked, a young man who is bright and, being an engineer student, would take the longest path back to safety in the dark, in a Nor'Easter storm, swamp, mud, marsh, snapping turtles, leeches, muskrats, slippery rocks, tangled mud weed, and green slime covered tree debris.
He'd take the shortest route back to safety and to the party house to clean up and maybe knock some heads around for being pranked. I say this too because, as I mentioned before in an earlier comment, perhaps the person(s) who pranked Michael had a good understanding of the layout of Maplegate Country Club's golf course. The tracking dogs tracked Michael's scent to Maple Street from the edge of Mine Brook. The area between Maple Street and Mine Brook is the golf course. Tracking dogs can track the scent of a person even if they are in a car being driven to a location. Perhaps Michael was driven into the golf course area and dropped off at the end of the course (which is near Mine Brook).
Now why would Michael, once realizing he had to cross a swamp (from the Bellingham side/Maplegate Country Club side) decide to trek it all the way to Catherine when he could cross over the brook and follow it (on the Franklin side of the brook) and get cleaned up (and some aid from cuts, etc) and some clean clothes to get home for Mother's Day celebration with some explanation why he was late home (and not looking like he was tossed into a swamp).
Think about it--he "played by the rules" as his 21-year-old friends said. His friend looked for him 8 times in the same location wondering why he wasn't there.
Michael may have tried from the marsh area to get ahold of his brothers early on into this "nightmare" (as one of his 21 year old friends called it) and that may have been the 1:08AM ping from the marsh area.
As for being pranked (and not wanting to upset my parents by my condition), and only speaking from my experience when I was pranked--I had gotten injured by this prank and I actually had my friends drive to a neighbor's house (who was a doctor) so he could patch me up so I'd be "presentable" to my parents who would have been upset for the situation I had been placed into.

As for the 1:08AM time of which you speak, I think you need to reread this comment (link below). You see, I was addressing another poster who brought up a reporter tweet error by the tweet stating a "fact" from a "belief" of the entrance point.

Edited to answer your question: HRP - Do you think the kids would hide this information of a prank gone wrong?
Yes. It would also be why the phrase "no foul play" has been hammered, it appears, in every report---even from early on. A prank gone wrong, from what I have found (I gave an example in an earlier comment) seems to be stated as "no foul play".
If Michael was pranked it may even be buried. The thing is, if there is an understanding this was a botched up prank, legally what can be done by the State? It would be up to the parents, I would assume. Unless there is some pranking gone wrong law that was broken. It wasn't a hazing issue. I think it's up to Michael's parents to pursue legal retribution or some kind of justice. If they don't want to, then what can be done? Drinking underage may cause some issues because Michael was under age. If they find drugs in his system, then who put them there--they'd say he took them himself (which I do not believe he'd do).
The parents of the girl (who was pranked and drowned in a swamp) pursued wrongful death suits against the parents and the kids involved and it was settled out of court. I had a link to this but it was deleted by the mod, so I won't put it up again.
