My friend and I found a way in one cold winter afternoon. We found ourselves in the middle of a large warehouse, with sunlight diffusing through gigantic windows to our right. We started looking inside of the crates, but saw very little of interest. My friend approached the far side of the building, and a cat leaped out from behind a stack of crates. My heart jumped, then calmed.

Next, though, an alarm over a door started going off. The high-pitched chirping sent us running back the way we came, and we exited - with difficulty - through the same place where we had entered.

We figured that the alarm was only to scare off prowlers like us. As we were driving away from the neighborhood, however, two police cars sped past us going towards where we had been. Their sirens were not on, but we did notice that a police station backs up to be in close proximity to the building.
