They are the support poles for the obstruction lights so we don't hit the
trees at night. I guess hitting a 4" steel pole is better than hitting
the top of a Douglas fir, eh? And not that we couldn't do a little tree
climbing and mount the light to the top of the tree so the light would
grow along with the tree? Naaaaaah.

Don't you DARE suggest anything that makes sense!

What color are the lights (red I suppose) do they blink, and how far apart
do they put the poles?
