I've got a quirt . . .
I hear they dye the river green on St. Patty's day (yeah, I know, it's March, not May, and COOLLDD, but that's the extent of my knowledge of Chicago, other than the fact that the majority of the overpass bridges are too low for most trucks--trucker newbies are actually issued a map of Chicago showing the location of every low clearance bridge, and suggested alternate routes! Nowhere else, not even NYC or LA, just Chicago.
