LoL... I love some of the answers here! To chime in....

I'd clear and fence in about 8 acres, build a small 4-stall barn, and bring my 2 horses home.

Fence in another 5 acres near our custom-built home for my German Shepherds so they can run. And run and run and run....

Build a nice insulated and heated pole building with lots of racks and cages for my herps.

The rest would remain natural with trails lacing through for horse-back riding.
