Actually, there are no neighbors on that side of our property. the other side of the fence is nothing but a gravel patch about 40 feet long, same length as the fence, that protrudes 15 feet out away from the fence. its just an empty area. it never gets used for anything, just a gravel patch with a few weeds and wildflowers here or there. next to it, 15 feet from the fence is the little road that winds through our neighborhood. i feel confident that this area is not playing a role in all this.
thanks for the nice compliment by the way!
