Personally, I would like to have at least enough to have a shooting range and not have any neighbors be able to complain about noise.
Since I can't afford that much, I live in a condo and have to pay to shoot at a range. If I'm going to have to put up with neighbors, I figure I might as well give up the illusion that I can do whatever I want on my own property and not have to mow the lawn myself.
My parents had 16 acres when I was growing up. It only seemed like a lot of land because the people that owned the land on two sides for a long ways lived out of state, there was woods and a pretty wide creek on a third side, and a really nice neighbor on the fourth side.
One bad neighbor could have made those 16 acres seem pretty small.
My wife and I are looking for a minimum of 20 acres but would like 75 to 100. We are done with neighbors or at least ones we can see and a log home just doesn’t look right in a subdivision...
