Cptlaury, so sorry to hear that.
Yes good idea, but if the scum look around your house and cannot find the keys they might ask you where they are....and i don't think they would be polite about it....if they want them they will get them..
The best thing you can do is make your house less attractive to the Scum..i know the Mini does not help, but, security lights, window locks ect....oh and a big dog
i have 3 dogs and they hear everything, they can bark loud, if you were scum and you heard 3 dogs barking would you go to the next house along (with or without a Mini)?
