The Power Station

Long ago, humans used to use this factory to produce electricity, but a fault in the main system made it dangerous for anyone to enter. Naturally, it was closed down, and no one has ever really got round to demolishing it. Large barbed wire fences line the outskirts, but dogs can easy wriggle under them, giving them a whole new place to explore. You can push the main entrance open, to reveal corridors and lots of little rooms, and at the very back, a huge engine room, where the power is produced. The old, rusted machines are no longer in use, so you can hide behind them, if you're willing to take the risk. However, all the doors up to the higher floors of the power station are locked tight, so you cannot live in any place other than the ground floor.
