I hate not being able to do something that in theory should be so simple. Shooting this or other shots like this challenge me to a level of frustration that keeps me wanting to come back for more. I have a friend on Facebook that will drive 7 hours at night to shoot a weather event (storm) in a neighboring state. He's like a beagle on a rabbits scent when it comes to that. I am like that for Fireworks! I get more satisfaction out of these shots that anything else I shoot...
