Any advice on what I need to know about country living/owning property?

I have 40 acres of rocks and trees on my hillside home for wayward dogs and noxious weeds. I Love it. I have about 20 vehicles in my salvage yard that nobody can see from the road. I built and maintain my house and other buildings all together about 5500 square feet if you combine the three buildings. My living quarters are only 1200 square feet, but I have a 12x20 deck just outside my bedroom on the upper story equipped with a hammock and a scenic vista. Covered porch below the deck with my grill and a couple porch swings. Stargazing is pretty good, I got a real good look at Jupiter a while back with my shitty telescope, and there is always the moon. The house/shop is insulated well and my utilities are cheap, wood heat with electric back up.

The best thing I have purchased for the upkeep of my yard/forest has been my Kubota bx24. It mows 5 feet wide, has a backhoe, box blade, weed sprayer, front loader, 4' bush hog, and garden tiller. The attachments are easy to take off and on once you figure it out, I don't know how I got along without it. Its kind of a mini tractor. It has 4 wheel drive and you can lock the rear differential with a foot pedal, sips diesel... It only holds 6 gallons or so and I only fill it up a few times a year- and I use the crap out of it. I made some ripper teeth for the bucket and can make some nice paths through the jungle with that and my little bush hog. You can dig holes to plant trees, dig ditches (about 5 feet deep), maintain the driveway, move rocks, pick up stuff and dump it somewhere else, level ground, move dead vehicles around, push brush piles, on and on blah blah blah.

Deer, rabbits, possums, coyotes, squirrels, all sorts of birds (even hummingbirds), frogs, turtles, snakes, lizards, bugs... lots of bugs everywhere. I'm in constant battle with the pack rats in my junk yard, but I think I'm winning right now. By the way if anyone needs something from a 70s 80s or 90s dodge truck I might have it.

I cant speak for you but living out in the sticks is great. I bought the place about 12 years ago and its been non stop ever since, always something needs done. Many times I have taken vacations from work just to stay home and work on my projects and dream up new ones. I hope I will never have to live in a town again, I am a happy man... except for the colon cancer, that sucks, but I'm winning against that too!
