In keeping with Bob's theme............here's a video of a strip that's on a mountain, or at least, on the side of one.
The video is taken from the back seat of a 182. In the begining of the video you see the strip, which has a 25% grade.
I'd like to add that as a student my landing are getting better and better, should I improve to the level of skill required
to land on this strip I will still have NO desire to do so. EVER
I apologizes for the few seconds of seat back video. There's a point at which looking though the camera is just not
good enough. The guy that flew us in there was amazing. I know there are a lot of great bush pilots out there, I had
just never flown with one.
