The skies are exploding with fireworks, the trick or treaters are out and kids all over the city are building bonfires.
And while most of them are small affairs, this one in Ballybrack is taking things to another level – literally.
The blaze is burning over 30 feet high as we speak, and you do have to wonder how happy you'd be with that only a few yards from your front door.
It's being described as the "biggest bonfire in all of Dublin"
Spare a thought for the services having to deal with incidents all across town tonight...

They even managed to set a roundabout on fire in Finglas.
How do you even do that?

And in Ballymun, the "old tradition" of the burning bush is well underway also...
