Brad,
You cracked me up with that comment about the rarity of lightning down there! I beleive i've captured not ball lightning but a plasma filiment emanating from the ground about 5 to 10 meters in front of my car. It occured with a cg that struck within 100 meters of my car on the left hand side and out of the frame, however i caught branches from the cg in the picture. The lightning was so close to my car that it's actually lit up the raindrops in the photo like a giant flash bulb!
I am however open to interpretation regarding it being a plasma filament or not. I was shooting through my front windscreen at the time. I know about the reflection effect with camcorders but I don't beleive it happens with normal cameras but you never know.
Jeff.
