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 Dublin 8 is talking things to another level – literally.
The blaze is burning over 50 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.
Spare a thought for the services having to deal with incidents all across town tonight...

And don't forget it isn't an enjoyable night for all...
Scary night for our canine friends. Hide them somewhere quiet and give them cuddles pic.twitter.com/MZQACrMO7a
