I was thinking that it's a good thing our founding fathers signed a Declaration in the middle of summer. Otherwise, there'd be some other stupid holiday invented for a reason to gift/camp/drink or eat our ways into oblivion. If some pagan ritual wasn't readily available to modify, then the greeting card industry would have thought of something. It seems that every month has a holiday, except August. Yes, we're going into the holiday dry spell.
While Labor day is towards the end of August, technically most folks attribute it to September. It's also conveniently far enough away for the gunpowder burns to have healed nicely.
