Mistras/Ropeworks rope access technicians replace incandescent lightbulbs with variable color LED lights on Dallas' Reunion Tower. The weather was bad, a severe thunderstorm warning was in effect for the first two days of my planned 3 day shoot. Jan Holan, head of Ropeworks, who hired me for the job fortunately suggested I delay my flight back, which is when the clouds parted and great light happened.
