Redneck Storm Cellar

So Sister and I are driving down the road and she says, "Is that supposed to be a storm cellar?" I, paying no attention, had no idea what she was talking about until she pointed it out. At that point, I CRACKED UP and had to stop in the middle of the road (because you can do that in Lynn) and had to take a picture. You've got to admit, somebody had a bright idea... then again, maybe they just drive like me and Grandma. :)
