OSH Arrival (You won't find this in the NOTAM!) 

Airventure 2017 arrival to OSH, went a bit differently than planned.
Ripon - Fisk - 27 downwind - 36L downwind - base - final.
We had reviewed the NOTAM that morning (again) and were well prepared (we thought).
Approaching Ripon, CTAF broadcast indicated 27 and 36 L/R in use. Lined up behind a really slow high-wing (90 knots? Pfft! Try 70!), and followed the railroad tracks towards the Fisk. Halfway to Fisk, ground tells everyone that 36 is closed (WTF?) and that everyone is going to 27. Okay, no problem...change freq over Fisk to ground for 27. In downwind and about to pull power back for base turn, we get word that 27 is now closed, and 36 L/R are back in use (double WTF?)
Everyone in the pattern for 27 is directed to go out over the lake, turn South on a wide downwind (right traffic) for 36 L/R. We do, turn base a bit late to make room for a T-6 coming in on the warbird arrival, turn final for 36L, cleared to land, touchdown, and GET OFF THE RUNWAY!
Welcome to Oshkosh. :-)
