Scott - Lightning & high voltage power lines!! It's a beautiful thing 8). I go after that sometimes too. I got escorted by security once trying to pull a shot like that. Did you hear the cracking & popping? A power line was really firing up for me one night in Sublette, KS. Green wintergreen Lifesaver sparks :shock:
Greg - that BLUE is incredible. Just after sunset I sometimes see the sky make that color and during Monsoon it's a photo op to be sure. I was on a storm in Cave Creek, AZ once and the sky made this electric purple I have never seen anywhere else...print, TV, neon tube, nothing matched it. Sometimes the sky does that. It is astonishing and a lucky moment when you get that on film. Nice work!
