What is the most interesting, unique, or challenging grass airfield that you have flown into? Why were you landing there...for fun, food, fuel, a museum, a fly-in, the people? Was it public, private, or not even listed on a sectional? How did you find out about it?
Interesting: Well, Wild Rose is interesting in that when Basler finishes converting DC3's to turboprops, that's where they go to train the pilots! I want to see that.
There's also Three Lakes, which has a VERY nice runway, on-field camping, and right across the street there's a restaurant, convenience store (more like a mini-grocery store than your average c-store), and boat rental.
Unique: Central County in Iola, WI (68C). Big hangar that says "built for the love of flying" and there's a fly-in (hopefully) lunch EVERY Friday. Yes, that's EVERY Friday, even in the middle of winter, even if the weather sucks, even the day after Thanksgiving, etc. If people can't fly in, they drive. A most excellent aviation community.
Challenging: 6Y9, when the runway was only 2000' and Ed didn't want us to use the first 300'.
After the first takeoff outta there, we all used the first 300' anyway.
I've taken off from much shorter runways (I think the shortest is Rio, at under 1100') but they didn't have so many trees quite so close to the end of the runway.
