Thanks everyone for the replies! This is a bit of a back-burner project for me so I may not respond very quickly....but I do read replies and really appreciate the advice.
That being said, I'm planning to go out there tomorrow to get the lay of the land. I have a list of stuff to check, note, photograph, etc., thought I would even throw out a few seeds just for fun, you never know. Topography, rocks, soil, vegetation, water, etc. etc. (Have done some checking with county soil maps, Google Earth, etc. Ponderosa pine and Douglas fir.....)
But - any other ideas to investigate / do / plant / etc. would certainly be welcome!
I've talked with a few folks I know and am getting a grasp on things. Thankfully a friend even knows the person who farms some of the neighboring land, so I will try to connect with him.
I've been to the county and done some records searching, no easements that I've found and the assessor didn't think so either on their last eval. I'm considering biting the bullet and having a title company check everything for me since they know what they're doing. I haven't verified any legal requirements on ROW yet, still on my (rather long) list. But someone I know IRL thought there was something like that too. (OTOH, serving a legal doc "by state code xx.yyy section 4, you have to grant me an easement" may not be the best first step in getting to know the neighbors

...)
Much more that could be said here but it's already late. I'm looking at this as an interesting adventure, learning experience, experiment etc., not necessarily homestead here next year or anything. Although I'm intrigued with the idea of a food forest, setting something up that would need minimal maintenance, etc.
So thanks again, feel free to chime in with more ideas, and (unless no one wants to hear) look for some more updates!
