Any guesses on what the barge behind us is for? (updated)

I think we are going to need ear plugs…. and we did!

As we were pulling into the wall in Waterford on Friday, we notice a barge heading toward us from the Hudson River. Of course they dock right behind us and it’s clear this is the fireworks barge for Sunday evening. No problem I say as ‘they would load them here and the launch site is waaaay over there. Yeah but… turns out they do load the fireworks right next to us and the water is too low ‘over there’ so they are going to just push the barge out into the water 100 yards or so and thus we have THE front row seats. I am a picture of calm as I make sure i have working fire extinquishers at the ready….
