Marc,
Thanks! That's what prompted me to actually photograph this. I'd been photographing about this area before and getting the (double) rainbow that was there. But, when I saw this thing, I had to get it. I've never seen anything like it, so close, too.
Bob,
Cheers! Sounds like you're a stormchaser, too.
Leon,
Thank you, muchly. I have not been fortunate enough yet to experience twilight lightning. That's next on the list -- would be pretty damn special.
Thanks, guys. I was wondering if I'd posted a dud.
