Wow, there was a sheet pot of planes at that fly-in! (Both of 'em)
I really never have understood the one way in/out at Gaston's. I've landed to the east, taken off to the west, the trees and power lines really aren't a factor.
Landing over the wires wouldn't be beyond the skillset of most, depending on their ability to use full flaps in something with effective ones, or a slip in something without.
Taking off toward them leaves less "outs", one of which would be quite risky --- going under them. But if the wind were howling out of the west and you started at the far end, in most of the stuff we all fly, would be well above them, long before you got there.
All depends on your performance numbers and whether or not you can hit the ones your manufacturer published after letting a test pilot do it a hundred times. Heh.
The other problem landing east generates is a head on problem since someone landing west who needs the whole runway is likely to be off centerline behind those trees at the east end, and would only show up as they angled onto to final through that gap in them.
Normal fare for uncontrolled fields but there's that little traffic detail also.
Probably help the takeoff numbers if the runway is dry and fast too, since we know folks here who've decided that "mudding" was always something they wanted to try in a twin when they visited the South! Hahaha. Or so I've heard. I would have paid money to have seen that... Ted.
Heh.
