A Clemson classmate and good friend brought a rock back from Death Valley, CA for me about mid football season in 2017. It is about the size of a large egg, and I rub and squeeze it during games. When I go to games, I carry it in my pocket and let those sitting around me rub it as the Tigers are running down the hill.
Does it work? I forgot about the rock for the Bama game last year, and we lost. That is the only game we have lost since I've had the rock. I told my friend yesterday that the rock was gray when he gave it to me, but it is brown now from the sweat of my palm. I laid the rock on my side table last night when the game clock read 0:00. It had done its job to perfection.
