If the storage facility advertises that they have cameras as a "selling feature" and not just signs on the fence as a theft deterrent you definately have a small claims court case on your hands and most likely their insurance will pay for your raptor before it ever gets to court.
Or maybe the cameras are real and it was an employee, or facility owner that stole it. If the units are gated often times they can see what other "unit renters" were in the "compound" when it was stolen. Often times there is a code to get in and that code is assigned to an individual or small group of individuals.
Good luck, someone needs a can of whoopass opened on them for sure:beer::beer:.. I hate when I work hard for stuff only to have some punk steal it.
