The same way I seem to always end up in trouble: Someone tells me it's a loop trail / path when it isn't.
Buddy, who rides a lot and leads a bunch of medium-paced rides, has been there, has done a loop - but we took the wrong turn (against my advice and Google maps). So what does one do when encountering challenges on a loop trail? One slogs through them to keep going - because of course it's going to get better again.
Narrator voice:
"But it didn't get better. In fact, it get much, much worse - and then they noticed that they had less than two hours of daylight left... and then they got separated."
Thing is - Google Maps has a white line that is a 'road' going through it, then it keeps going. With my phone screen being smaller as it is, and with very little connection out there for good resolution of google maps satellite view (which I was using), it looked for every intent as a dirt road that would get better.
Looks like swamp buggies (not even jeeps - actual tall swamp buggies) forged the trail after seeing it on the maps. Most of those made the little loops at the end to turn around, but one of them blazed a path to follow what google maps was showing... and he had to give up and merge back with the way they came in.
That's the thing about google maps, gravel biking, and Florida - Google maps has seemingly accumulated every road that was ever planned and mapped it. One can get to those places and find a ranch, a road that hasn't been used since 1950, or nothing at all. And you just don't know until... you know the hard way.
With better connection I would have tried to look at Strava satellite mapping of the area. Strava satellite map images have generally proven to me more updated than Google. I'm not sure why Google Maps has slacked off on updates for satellite images so much, but it is no longer considered reliable.
