Lowell,
Good news....the airport you landed at is unequivocally 2C4 (Chatfield) as Avidflyer suggested.
1) Around time 1:40 on the video - check out the three silos on the other side of the quonset barn...Two with round tops and one without.
2) The hangar with the trees in the SW corner - that's it. I believe the hangar has a newer white roof now.
3) The funny shaped row of trees south of the departure end.....that's linear/crescent shaped sinkhole.
If you have some footage of the area north east of the silos/barn across the road - there is a whole family of round shaped sinkholes. Can't farm sinkholes for crap - so the older ones get trees.
Google earth it.....works out.
