Helping to set up fireworks for the 4th of July?

Last year right after the 4th of July, one of my kind readers offered to let the me and the boys help set up and set off this year's 4th of July show in or around Portland. However, I can't find who offered. If that kind reader is still out there, can you drop me a line? I'm sure my 60-year-old father would like to help, too. Thanks!
