Right as the wife & I were building this house, we had an incident with some neighbors 'walking off' with new, unused lumber from our build pile. We reported it, and the county Sheriff's office went over, had a nice talk about thievery etc with said scumbags.
Shortly after the county had that talk, each time we were in the field behind our house hacking away at some storm-downed trees with my 14" Stihl saw, the man/wife team of theives would come out into their yard (adjacent to my back field where the trees were downed), set up a couple targets, and start having their weekend target practice sessions. This went on 3 weekends in a row. Each time they heard my saw fire up, they would come out with their rifles and start blasting away at their targets. They had over 5 acres to set up practice, but chose right adjacent to our fence line to do their shooting. At no time did they ever point at us, but with both of our lab retrievers running to and fro, plus both my children outside helping us tug limbs around, it really was annoying. Each time this happened, I'd pack the saw away, and we'd go find something else to occupy our Sat or Sun morning/afternoon. No doubt this couple were trying to intimidate us, the new neighbors.
The 4TH F'ING WEEKEND IN A ROW this happened to us, we silently packed the saw away. Put the dogs in the house. Then I stepped out onto my back deck with the old SKS loaded with a 20 round clip. I sighted safely down range into the back slope of my land, safely adjacent to where they were still holding their target practice, and let fly with all 20 rounds. All of a sudden, they didn't like being out there any more. Who knew the neighbors could move that fast.
The following weekend, I managed to continue chipping away at the large downed trees without any further intimidation from my thieving neighbors.
