These are two of my favorite pictures. I was extremely lucky to be driving down the highway and catch these guys working in the hills. I had my 200-500mm lens, which allowed me to take these shots. It was all shot out the window. I sat there for hours, watching these guys work. I would like to do this after I retire. I respect these pilots greatly. I was able to contact the pilots via social media and made sure they received copies of the prints.
