We have an elderly couple that live right next door to us. The gentleman is an avid birder and the woman is an avid gardener. The combination of an elderly couple with hobbies like this and my family with a bunch of kids who like playing active games outside (usually involving a ball of some sort) have led us to the realization that we really need to look into fence installation to preserve everyone’s sanity.
They’ll be happy with the lack of balls in their yard, I’ll be happy not to hear about balls going into their yard, and the kids will be happy to have a nice tall fence to bounce their balls off of.
