Still a ways to go here on the W slope. A uniform set of rules and plating would go a long way to unravel the confusion with a zillion juristictions and laws. Add in BLM, USFS, LE, who are almost always cross deputized, and it can get confusing.
Example: I live in Saguache County. Let's say I want to use the Hartman Rocks trail system and rock climbing area in Gunnison County, which is about 6 miles away and is like a mini Moab. I use subdivision roads (OK, but could be subject to subdivision approval). BLM roads usually signed and OK, but could be subject to seasonal restrictions. Saguache County roads, don't think they give a bit of care to the issue as they are possibly the least bureaucratic County in the state. Saguache County roads with conflicting BLM easement claims that may be resolved some decade in the future. Gunnison County roads maintained dirt but I guess it's OK since I've been driving them for 20 something years with no issues. Gunnison County with BLM claimed easements. I have to use the back entrance to the Hartman Rocks facility which is a mix of BLM, County roads which may be restricted....or not. The front is pavement which is restricted.....unless your the local rancher who drives his UTV on to because agriculture. Clear enough?
I have crossed 4 (possibly 5 becauseHartmann Rocks is Joint jurisdictional venture) different juristictions to go 6 miles.

Asking LEO for clarification brings an eye roll and "just be cool about it."
