The roof of this old barn is covered with lightning rods. Some people swear by them, others claim they just invite lightning to come for a visit. Do you know of anywhere that lightning rods are still installed on a building? They seem to be less and less common. I remember as a kid they were on the roof of many people's homes.
Here's an explanation of the concept of lightning rods:
http://science.howstuffworks.com/nature/natural-disasters/lightning7.htmBen Franklin is credited with inventing the Lightning Rod. Another of his oft misquoted but very popular concepts relates to fermented spirits, “Behold the rain which descends from heaven upon our vineyards, there it enters the roots of the vines, to be changed into wine, a constant proof that God loves us, and loves to see us happy.” Good enough for me. Wonder if you can still get people to install lightning rods?
