We were at a BBQ. About 8 the first fireworks were lit. Cheryl turned around in her chair to ask if it was time to go and I was already heading up the walkway. About half way up the walk some A hole threw a M-80 the other direction. It echoed across the lake setting off alarms on the other side. I got to the car got in and waited for Cheryl. Went home turned a couple large fans on high put them about three feet away and went to bed.
