Free Rock. Pickup at the end of my Driveway. Thanks for looking.
No phone number or address. I guess I can just cruise around [Location] until I find a rock that matches the picture. Hello, I’ve come to look at your rock. No, that’s not it. I will have to give Sparky a bill for the gas required to pick up this free rock. Ralph points out that rocks are not that rare in this part of [Location].
Welcome To Fabulous Sparkyville
