The sign on the electric fence at the spot where the trail heads down through the woods.
I don't know why our town does them on Sunday night, but it's not the first time. It may have something to do with people having to go back to work the day after the 14th, so staying up late for fireworks and the party after on a "school night" may not appeal to some. I don't know how many people use the expression "school night." It comes from kids not being allowed to stay up late at night so they can get up for school the next day. I guess it carried over into the working world.
