Probably stating what's well known, but Grant's Tomb's post makes me think of degrees of separation. Field of Dreams includes scenes from "Chisolm, Minnesota" that were filmed in Galena, Illinois, the site of two homes of US Grant.
Galena is a very cool town to visit. I was there two years ago and climbed up and, after walking past Grant's first home, later descended all those steps in the Ray Kinsella - Doc Graham scene. My calves hurt for days but it was worth it. About time to watch that movie again. I'm sad that Mookie Betts' outlandish new contract has finally put me off the modern game.
