Oh jeez.
The annual cleanup is going to suck. Cleaning debris from the neighbors' fireworks from my gutters, driveway, yard is gonna suck extra special this year. Maybe I'll luck out and there will be a strong wind blowing it back in their yard.
They don't clean it up?
I always clean up their yard that night and in the morning after.
Get get a decent amount of fireworks, and usually the neighbors watch from their own driveways while I destroy mine.
