Just a personal thank you to Dr. Silver.

My paternal grandmother's family was rooted near Cynthiana, KY and the 3M Post-It-Note factory brought a lot of prosperity and middle class jobs to this very rural outpost. My Uncle would always keep a pack of Yellow Post-Its to show "Made in Cynthiana" on the back, a sign that the little town he spent his life in brought something useful and ubiquitous to the world.
