I grew up just across the river from New Madrid, in the same county (Fulton) where this project is located. That quake in 1811 sure improved the real estate by creating the marvelous Reelfoot Lake, Tennessee, mere minutes from where I lived. Frequently, though, the jam would fly off of the shelf during the many minor quakes.

I lived in Gibson County when I was a kid and one of my earliest memories is of my parents taking me to Reelfoot Lake on picnics and for Daddy to go fishing with my uncle. My husband, son and I went down there a few years ago to see the eagles in that area. They were having a few little tremors at that time.
Hey, I'm going steal that from you: "The jam is gonna fly off the shelf if you do x, if you don't do y or if momma finds out about z"
