Treadway's Rock

About a week ago, I pulled into the Costco gas station to get gas. I saw the attendant talking to a lady and walking around with a trash can. I was hoping he would not come over and start talking to me. That stuff just bugs me. I know it is their job to ask if we need anything but it still bugs me. So just like I did not want, he comes over and says "did you know the Treadway's Rock"? What! I thought how did this man know me? I turned and looked at him and said "OK". Then I looked at my back window of the Suburban where he was pointing, someone wrote, "Treadways Rock" on the dirty back window. I guess I better do a better job of keeping this car clean so that little fingers can not write our name and display their feelings. :) Thanks Talissa.
