This is of the Exton, PA fireworks finale taken July 7th, 2007. I was there with Bri, Joe and Gino along with their families. The screams near the end are from Bri. As you can hear, the video ends just as Gino is starting his trademark "wolf howl".

He carried that howl for a good 30-40 seconds at which point everyone had stopped cheering and were simply staring at him. The silence was broken when someone started slowly clapping. Then everyone started clapping and cheering wildly once again... but this time for Gino.

(I think all fireworks are better with a good story. Or even a bad story.)
