I live in Ireland - a place where thunderstorms are rare! When I was living in the states for a while, especially in Utah, I witnessed a crazy storm that lasted for hours. I was sitting on the balcony with a friend of mine and some beers until it got so crazy that we had to move inside. I did not even dare to have the tripod on the balcony all the time, fearing the lightning might find its way. Ultimately, it was a night I shall not forget so fast.
