“It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.” – Mark Twain
A few months ago I attended a High School soccer match downtown which was scheduled to end just in time to get the spectators (who were largely from the suburbs) out into afternoon traffic. As the game wound down the usual debate began amongst the local traffic experts sitting in the stands about how to make the 25 mile drive back to our home town. “Take I-40 straight to 67 then go on up,” says one. “You’ll be stuck for an hour that way. Better to go through town and up I-30,” retorts another expert. “I never go that way at this time of day! It’s sure to be backed up,” says a third. I watched in fascination as these guys speculated as to the likelihood of traffic delays and the usual traffic patterns. No consensus was found and I was interested as to whether this was going to turn into a live experiment after the game.
