The reason Tulip Poplars are prone to lightening is because they are
generally the highest thing around. The one next to my barn/shack is now
110 feet tall and dwarfs my 80 foot towers. It does a nice job of holding
up a 75 meter delta loop tho. That tree was one of the main reasons I
bought this piece of property. 73 bob de w9ge
