Ours was very quiet, just my core family unit. It was nice though as my husband isn’t always able to be with us.
My small herd is very lucky to have a gentle, imprinted gelding as it’s lead. He really doesn’t get concerned about the weird things humans do including fireworks, so the herd doesn’t either. Our neighbors were setting some big ones off across their fence and the herd was calm. I know that some horses have had rough experiences and am so sorry for that.
