However, the complaint was reception of an LA area station 
in San Diego, so that was not the point in this case.

I don't doubt your observation because there are some cases
of daytime IX with more to come. However, the same problem 
causing these cases will be compounded by skywave. 

This may be a bit cynical, but ultimately the only protected 
coverage is going to be that in the COL or SMA, inside the 
5.0 daytime and established NIF or 5.0, which ever is greater,
at night IMHO. Then, it would seem to be a significant 
economic issue that can't be brushed aside.
