Safe?

I've only been once, several years ago. Seemed fine. The parking lot has a high chain-linked fence, as I remember.

The place is located in an industrial area. I feel safe, although I only go there during the day. Never been patted down there. They recently put in a metal detector after you pass through the doors. When I go in, nobody is around, so I have no idea what purpose this serves. I assume this is a night thing.
