Awesome! I agree with Alicia, I would've guessed a thousand things before fireworks, most of them in the scifi dept. Hehe Amazing pic and great subject!
Maybe not as dramatic as your other shot, but still striking in its rarity. You sure got luck on these...the water is so still it's like a mirror. Thank you so much for sharing these with us.
The only thing I might have done differently would be to crop in on the contact points and the arc above them...but that might have made the image too difficult to bring up to size.
