The PGA Tour has been on the East Coast enough, so they move to the Illinois/Iowa border to play The John Deere Classic. The course is TPC Deere Run, and is a par 71 at just over 7,200 yards. (Side note: another course where par is less than 72... I think this is the norm for the Tour unless you can stretch out the yardage to 7,500 or larger. A marker of days to come).
The tournament is held in, and benefits, The Quad Cities. What four cities those are, I have no idea. Moline and East Moline, IL is a real thing apparently.
