dear female hikers and hikers, mountaineers,...
12 years I worked as a criminalist and have a lot of experience among others with property crimes (break-ins into vehicles,....) As far as I know, to the parking lots where mountain visitors park, for the purpose of breaking into vehicles, gypsies come from Dolenjska, Bela Krajina, Posavje and maybe from somewhere else (I'm from Bela Krajina and I know this, even romani informants told me that their gypsies go breaking into vehicles "where Kekec lived"). They do most car break-ins, they break in very professionally so you don't notice the break-in right away at all, but if it doesn't work, they usually damage out of anger.
On parking lots pay attention to vehicles of mid and higher price range, reg. areas NM,KK,LJ, in the vehicle at least three or four, some don't even have gypsy appearance. When preparing for the trip or back from the trip, be alert to NON-HIKING BEHAVIOR (a hiker immediately sees who came to the mountains and who has no business here, sitting in the vehicle, talking, walking around, one standing aside observing,...), mandatory note down reg. plate, make and model, color of vehicle, number of persons and report this data immediately to 113!!!
Perpetrators have the advantage that they come from somewhere else (at home we caught them and they don't break in here anymore, so they go elsewhere), break in and leave immediately and it's practically almost impossible to track them, or later prove the criminal act, as the victim usually discovers the break-in only a few days after, when it's hard to do anything anymore.
Don't leave valuables in vehicles!!!
I myself have encountered gypsies from Bela Krajina in Vrata, their hair stood on end when I asked if they're going hiking with me, they left immediately.
good luck and safe steps, Muša
