Even Forrest Gump thought that. I dragged my feet, but logic & chart won out. Guess I'm a little dumber than Forrest.
As an aside, poking around Google Earth, I learned that there are places in AZ named "Red Rock Canyon" & "Robber's Roost" . . . . very far away from Tombstone, LOL! Alas, no "Earp Ridge" in that Database.
