I haven't done an update on this since the initial post, but since this is effectively the runway thread, but was inspired to after this weekend.
Back in November 2017 we had some friends over for the "Kansas Chainsaw Massacre" where we cut down just about all of the trees needed to clear the strip. I say just about all because there are a few more we'll probably cut down just to make it a bit wider in certain areas for a bit more safety margin. Also, the pond has some trees on the far side of it that I expect we'll cut to give some more room.
The hydraulic return line popped off the front end loader and it was beer-thirty that day, so we called it a day, although I didn't get to clear as many trees as I would like. Then a hydraulic ram went out on it, and so I had to get that replaced which was a whole fiasco. Cleared out the chopped trees, and then came the question of clearing stumps. I haven't made much progress on that yet, but we did get the bulldozer and that's the planned implement for clearing at least most of them.
There's a lot of work remaining on the runway, but I expect that this year we'll clear the tree stumps and get some prep work done to get the land such that it could actually support an aircraft landing on it - going over it with the roller, maybe some level of flattening/grading. And of course building the hangar and buying the airplane to put it in.
What prompted the update was that yesterday I took a video of driving the Farmall H up the runway, at least in its current state. You can see a lot of tree stumps sticking up. Obviously the trampoline will get moved, but no point in doing that now since we're a ways away from needing it.
Anyway, it's a long video as I was driving pretty slowly as I was towing the kids along on their sled behind me. But it's a nice peaceful video, and shows the runway. For reference, at the start of the video I show the end of the runway with a dirt pile (covered in snow) and then drive up. Note there's about a 3% grade, and I'm going the uphill direction, so this would be the direction I'd go landing. It's about 1,000 ft.
With the snow yesterday, that convinced us that we should think about skis for whatever we end up getting.
Enjoy!
