It's been slowly dying off here. Some of us have older kids, but a lot of the ones with younger kids just don't take their kids out, they're too busy with the B.S. TV show of the moment or whatever. We had maybe 20 kids or so last night. There might have been 2 dozen houses in the area with a jack-o-lantern or other decorations out.
I think it is the same for a lot of holidays, if there's nothing in it for them, people don't do anything.
Out of maybe 40 houses I can see from my house, maybe 3-4, no more than 6, will have any outdoor decorations for Christmas, either. Mine will be decorated, and lit up. We do that, and spend money entertaining friends and family, rather than being hung up on the material side of it.
Same with fireworks for July 4th, and New Years. There was a time when everyone shot at least some fireworks, regardless of how broke they were. No more.
