I took some pictures this weekend of fireworks using a long exposure time. They came out pretty neat, the only down side was we didn't have a clear view since we got to the park kinda late. Oh well. That is one of my favorites. If you want to check out the rest the album is here: http://imgur.com/a/5apaD
^^The one you posted was from the show on the second. ^^ From the 3rd (& my fav from this year I think) ^^ From the 4th.
Herr's Potato Chip factory in PA, they do a big thing called Freedom Fest with Nottingham Park every year.
