Same here! That's why we bought the old farmhouse.
And save-y folks! 
 
Yup, same here.
We bought our house with 8 acres. One of the neighbors offered us "the field" when they decided to sell, because they knew we wouldn't build on it. We wanted to keep it the way is is. They gave us a bit of a deal, I think. We bought "the old farmhouse" when it went into foreclosure for the same reason: we didn't want someone to put 3 houses out there.
It may sound a bit NIMBY, but land is getting bought up and "developed" all around here. There are more ways to use land than to try to wring every last dollar out of it.
