If I'm going away for a bit I park a bunch of cars in my driveway... the only way to get the bike out of my property is through the garage door, and down the driveway. If they wanna move a bunch of cars without neighbors or roomates noticing then break my 2 locks on the garage door, then get one of my bikes then they should find a different outlet for their effort.(once in the garage my tools are locked up but they could easily get into those and use them to get the bikes started minus the keys).
I think she's got the house covered.
If someone makes it up the driveway, the dogs are sure to get them.
