Fireworks 2022 - Blue Streamers

I spent the night watching this guy lighting fireworks off his dock on the Piscataquog River in Goffstown, NH. I would hold my remote shutter release, thumb on the release button following this guy's light. Once I saw a second light (his lighter) I would open the shutter and count to three. Not real technical, but it worked. Blue streamers are not something I was seein gmuch of this night, so glad this one worked out.
