Suspicous black BMW car last night

Last night round 6:00PM there was a black BMW car pulling round all of our buses. I back into the bus bays, and shut the doors. I spyed on them untill they were gone. They took a look at bus 074. I'm not sure why this accured but it did. I will be more careful untill i know 100% that they will never come back. I also will be installing a gate in. each bus will have a door opener clipped to their sun visor. Press the green button to open and red button to close.

Thank you for the heads up Nick, we will depend on you!

We have 10- Foot barbed wire fences guarding our base, how the hell did they get in?

not sure but they will not be back because of me.
