The one time I flew in they were spitting runways at FISK, you couldn't know which runway you were going to get until you were there. You have to have a clear metal picture of the NOTAM to avoid getting flustered.
One fun thing to do is to visit FISK on the the ground. I've done that several times, the controllers are glad to share their experience with you.
I swear, those OSH controllers have the patience of Job. I couldn't believe the idiocy that they put up with. Pilots showed up totally lost, pilots who never heard of the NOTAM, pilots who insist that they be vectored to final ahead of everybody else, pilots who won't shut up on the radio, etc, etc, etc.
