I have had beverages here in EPA for many years and have always found 
the west beverage to be noisier that the NE or SSE beverages.  I have 
always assumed that it was due to the many lightning storms that 
occur to the west of me.  That may not be the case, however, since 
the storm capitol in the US is southern FL and that is SSW of me.  Oh 
well ...!
