Storm chasers who have seen ball lightning?

[Ben Mitchell]

I am almost 100% positive that ball lightning does not exist. What I presume to really be happening is lightning striking a transformer (Seen in post above)

About 20 years ago, a brother of mine was in the garden of a cousin when lightning struck a house or garden in the street. It was a very bright flash followed immediately by a loud cracking boom such that the windows were shaking. Some neighbors told him that they saw a ball lightning rolling down the street for about 50-100 meters, originating from the place where the lightning struck. The nearest powerlines were maybe 30 kilometers away so I dont think that they had anything to do with it. But maybe it was just their imagination or something else. I wish I could see it myself someday. It looks like it could be caused by a powerful positive lighting strike.
