I'll do you one better. I have a 3000ft private grass runway in my back yard. I have backstops built at about 30 degrees to the runway on the far side where I dug the drainage ditch. I have targets at 50/100/150/200/300/400/500/600/800/1000 there, and from 0-50 directly behind the house. I have a shooting bench built into the back deck, which is just off the reloading room.
This came about out of necessity. The three ranges closest to me are more than 40 miles away, one way, and average $15 per hour to shoot.
I keep the range pretty private, for insurance reasons, but I do occasionally allow a few guests. I have had so much trouble in the past with people showing up thinking this was a "public" range that last year I put in $12,000 of 8ft hog fence and a remotely operated gate, and even had to dig ditches to keep ATV's out.
Believe it or not, it wasn't that expensive. I bought about 50 acres that borders lumber company land cheap, traded some electrical work for use of a track hoe and dozer, sold some pine timber, and built a small house. I have about $250K (financed) in the whole thing, including the house.
Glad you have a good place to shoot. They're becoming harder to find. Sounds like you better get busy loading.
