Basement. My own room, walled and closed off from the rest of the house. She gets total dominion over the house except for that room.
I have a computer (reloading and ballistics programs), a TV, a radio and a fridge.
I currently have two benches for reloading, and a cleaning bench.
BTW, the mess here isn't mine, my Brother and Father load here too, they're the messy ones!
