That sounds good, but I don't know where to start on that. Does anyone want
the 28R light structure to play with? It's here:
http://home.comcast.net/~davidculp2/28RLights.ac
And the placement info goes in Scenery/Objects/w130n30/w123n37/942050.stg :
OBJECT_STATIC 28RLights.ac -122.35186 37.61125 -0.1 62.0
Here are some photos of the real thing:

If we can get the light-hiding problem fixed, then I'll make light support
structures for all of the KSFO runways that need them.
