I'm not too fussed, frankly a good techno whizz with a few warez apps could track your IP, slice through the basic windows firewall and rummage through your files with more ease than your usual smash and grab neighbourhood ass can manage to get through your open window.
There's more stuff on there than on here.
Besides, to rob this place while I'm gone, he'd have to get through a passel of unsocialised farm dogs with sharp teeth and a "this is MY place" mentality to reach the machinery storage, through the rest of the farm workers/owners and there's ALWAYS someone on the farm every day, maybe not in the house, but somewhere on the farm. It's 3Km at the far end of a dead end one lane gravel road that winds through a gorge. One tractor parked on the road by devils bend and any thief seeking escape will have to climb a 175 meter steep bramble covered bluff, or dive 30 metres into a foaming white water mountain river...
I think you could say, I'm not worried, too much hassle for a thief here when there are lotsa houses in town waiting for them.
