Still, some thirty of my neighbors' fences built with wooden posts

standing.

My first thought when I saw your post was that one side of the
right-of-way was upwind and the other was downwind. The upwind side
would be in the wind shadow of houses and trees. On the downwind side
the wind would be able to get a little meaner as it passed under the
power line towers.
