I can add my own story to Tom's.  In my case, I had a high-tension line 
about a mile south of me at my last QTH, in central NY.  I could always 
find an increase in the noise floor from it.  

Perhaps some *are* cleaner than others -- but I've never seen any signs 
on the tower legs saying which ones were the "clean" ones....
