Being July 4th, I thought it would be appropriate to post a photo of fireworks. This was taken in 2003 at Gas Works Park in Seattle. You can just make out some of the original gas works machinery at the lower left, and just some of the tens of thousands of people in the park on at the lower right.
Even more people are expected for the Lake Union show, since the other large fireworks show in town over Elliot Bay isn't happening this year. The biggest impact will be on the surrounding Wallingford community, since the park will probably be closed to more people walking in after it reaches capacity. The overflow will end up on the streets of Wallingford and even most likely on private yards. Because of the location, people will also be able to see the show from all around Lake Union, including on Queen Anne Hill.
According to a Seattle Times article that ran this morning, the Lake Union show will use two barges to launch the fireworks. The people running the show didn't start loading the shells until July 3rd, which means a very busy two days. It's a lot of work for a 20 minute presentation, but it's always a great show. Even though it's going to be packed at the park, the year we went we had fun "ooh"in and "aah"ing along with all the people around us.
