Well, this is known to most chasers but it is as close as you can get: (nb. if you are opposed to foul language, better turn the volume down!)
http://www.youtube.com/watch?v=Z3WJt2shAmsWondering whether any of you have been close to being zapped, chasing or otherwise? I have to say, in almost 10 years of chasing, I have not. Over the years, I've had numerous flangs drop well within the 100 metre comfort zone, but have never had the feeling that I was actually the target! eg I rememeber one CG which which struck a 2 storey apartment block about 10-15 metres from where I was parked such that my car filled instantly with an odorous gas (I should add, this was not as a result of my bodily response to the deafening blast of thunder either!). I don't regard this as a close call as per the above clip and, other than the stench, I did not feel anything unusual.
I also remember when I was young, one occasion where my Dad and I were about to leave his work when a CG struck some metal directly opposite us...say about 10 metres away on the opposite footpath. The thunder was deafening and before I jumped back, I saw the sparks and blue flame on the ground and heard all kinds of sizzling and crackling sounds. I suppose that is pretty close but I did not feel any static electricity build-up probably because we were under an awning. I know Jimmy was almost perilously close on one occasion.....
