Hi there!
Sorry you ahve 2 adult kids who are causing you a tough time, I only moved out at 24 from my parents, but I paid board and did my share! Get your kids helping on your farm, it sounds lovely where you are. I would love the land to keep horses (I used to compete in show jumping here in the UK, until I had a bad car crash!) I really miss horses and living in a city means no spare land!
Happy planning too!! xxxxx
