My experience is if you aren't there to watch it on a regular basis somebody is going to screw it up, steal anything worth stealing and/or dream up some way to grab it.
I've got three plots. On one the closest city has been trying to immanent domain it and at the same time the Park service has been trying to grab it, it borders a State Park. The city says they want to build a school there, which is insane, the back of the property is a two hundred foot cliff that periodically sheds bus sized boulders. The park service discovered I have water and they want it. I'm seriously thinking about Deeding it to a local Indian tribe before lawyer fees eat me up. I've declared it a Saquaro Cactus refuge, we will see how that works out. The closest city was a few buildings and a dozen shacks when I bought the property, now it is almost a suburb of Phoenix.
Another plot in South Carolina is constantly encroached upon by my neighbors. When they plow, they plow an extra thirty-fifty feet onto my property every year and slowly try to expand their holdings. The same plot was raped by a pulp mill a few years back. I figure I'll eventually loose it to development. I did one smart thing, I buried an old engine block at the four corners after a survey and can now find my property line with a metal detector. It used to be in the middle of nowhere bordering a highway, now suburbia is headed my direction. I've declared it a bird sanctuary.
My third plot is now the go to place for dirt bikers and ATV drivers. It is high desert anyway and not much grows there, now it is a true desert and only grows trash. The only good thing about it is it borders a major aqueduct and would be a good hideout if TSHTF.
