I had some focus problems and I think wind may have caused some camera shake with some, but I got a couple of good ones. And now that I've finally tried shooting fireworks and encountered the problems myself, next time I'll do it better. These were shot up on "the bench." That's up the slope of the Wasatch mountains that rise up out of the East side of Salt lake City. I believe the mountains in the background are actually Antelope Island, in the Great Salt Lake.
