Out my front door! I'm not kidding. My wife & I looked until we found land in a place we like, at the end of the road. We even make our own electricty! I currently have a 200 yd range, next to state land (I could get 1,000 yards by shooting into the state land, which is legal).
Next month, I'm going to move and raise my backstop, so I can get 600 yards. I have no one living within 1/2 mile. When I start shooting, folks over the hill open up as well.
It's great to live in the free state of Arizona!!
