Not anymore. We also live in the middle of nowhere, leave our doors unlocked, garage open, but have three dogs inside that will chew you to pieces if we aren't here. Outside, they are pussycats. Since we have about 100 houses on our 12 miles of road, we pretty much know who is visiting and who lves here. We all wave to each other and eyeball the strangers. Most own guns for various reasons too so that keeps most at bay.
