Where is it?

Rural folks who use a post office box number for mail delivery instead of a street address have told me that UPS and FedEx drivers sometimes have trouble finding their houses. I was at the Unionville post office the other day when a worried-looking young man came up to me and asked for help finding the La Mancha Animal Rescue. He was on his way to adopt a pet, and his GPS led him to the post office, because the good people at La Mancha have a P.O. box as their mailing address.
Fortunately I knew exactly where La Mancha is and could give him directions. I hope he made it there and was able to give a pet a "forever" home.
