Boy was I surprised when I opened this thread. With a quick glance I thought the title of the thread was NFPA (National Fire Protection Association) the ones who publish the National Electrical Code. (see my user name)
For a brief moment I was excited that someone had posted an electrical question on this forum.
In honesty I must admit that I was still impressed with the shooting abilities that are reflected by those pictures, many thanks for them although I was mistaken when reading the title of the thread.
