Crawl/Offroad Routes and Trails

SO I've had some fun with BeamNG for a while, but I'm quite struggling with off-road trails. I'm sure the game has some quite challenging ones throughout, but I'm struggling to just find some new ones. Where are you're all favorite unmarked/unknown trails that aren't as easy to find?

For example, on JRI I only really know of 2 good ones - the one that runs up the river (eventually ends near the waterfall/dam and the one that goes along the ridge (past the airport), yet I'm sure there are quite a few more along those lines.

 

In Utah, the rock ridge that hangs off of the cliffs is actually a very, very lengthy trail.

 

Near the tourist center, there is a nice crawl that is a bit like the "Chute" in real Utah, its not marked but is just off of a trail. After the bridge that goes over the river in Utah, just at the second curve, if you can make it up the dirt there is a small crawling area. All around the airfield in Utah there's a bunch of little areas that are good for either hooning around or crawling
