Beautifully expressed, Dan.  You are certainly correct.  The patron
saint of sailors is St. Elmo.  St. Elmo's fire is the glow sometimes
seen when the static potential between ground and clouds becomes great
enough to cause a steady discharge from elevated conductors, such as the
spears of Hannibal's soldiers.  If you are on the water and see St.
Elmo's fire it is high time to head for shore.  Any elevated conductor
on the water is a tempting target for lightning.       Elmer
