Firecat Masquerade were a marvellous collective of creatives who ran pervasive games, immersive experiences and the like.
They had the utterly fabulous idea of “What if wind in the willows, but post-apocalypse”?
I can’t find much about it, but…
I can remember our group concept was a group of weasels who’d escaped from prison dressed as washerwomen. Because how else? I can remember getting very competently murdered minutes into the second event, on the orders of Mayor Chief Boggart Weasel (I think?) and playing a psychotic rabbit the rest of the event.
But at the first event… We had a little car, and we’d give you a ride in our little car, and murder and eat you if we could get away with it. (one us had just put on Bugsy Malone, and we trailer’ed the prop car to site.) And we wore grey striped “prison uniforms” with our disguises over the top and were investigated by the badger magistrate.
As Martin Cutbill, who made this video and found it the other day, said – “Still one of the very bizarrest experiences I’ve had at a LRP.” He also says…
Things I remember about the car: The in-game currency was ‘meat’, which was made out of Rabbits which functioned as a very separate PC character class (mechanically as well as in the setting) to all the other animals as a result.
So I remember our call was ‘Who wants a car ride? The fare is one meat. Rabbits ride for free.’
LARP experience 
Ah, Winter in the Willows. One of my first systems to ref. The website is long since fallen over, but the livejournal page (2010, what a time) stands as a memorial to the original concept. So much of that system – especially the music-based detect-magic concept that Dan Avery put together – need a place at a newer system.
The place is Berkshire, what is left of it – the overgrown outflung arms of the Wild Wood and the ruins of London-That-Was.
The date is unknown, not that it ever mattered. The time, for now, is not Winter, although every living thing pays heed to Winter’s cruel advance.
What is known – what is passed from animal to animal – is that it is 200 years since the Knifewinter wiped human civilisation from the Countryside. Taking their chances, the Weasels seized London for themselves, setting themselves up as lords of all. The Moles dug deep, digging new tunnels and mines; the Ferrets moved to the roadways in their brightly-coloured wagons and the Stoats retreated deep into the Wild Wood, to become something cruel and feral and fearful.
Although 200 years have passed, most of the Animals do not possess the drive to Science that characterised humanity – and possibly condemned it. As such, all that remains of them is the 19th-Century ruins they left behind, as well as their technology, fashion and a bare few of their ideals. The Animals have made the best of them.
Now, the Toad scientists and Weasel street-gangs define the heights of “Fash’n” having seized control of the dying breaths of Technology, in vast factories managed by their Rabbit slaves. The Moles and the Hedgehogs jealously guard the few tattered Manuals and devices they have managed to scavenge. The Water-Rats and the Ferrets control trade on the rivers and the roads. Deep in the heart of the Wild Wood, the solitary Badgers have clung to the vestigies of Culture, building havens of Civilisation in the dark between the green.
The less said about Foxes, the better.
The earliest years of the 20th Century were the last years of humanity. Now, some time on, the animals of The Wind in the Willows are distant memories, or perhaps legends, and their descendants eke out a living in the Countryside that the humans left behind. Twice a year, they meet at Country Fayres to negotiate trade, share ideas and gossip, and if necessary, to hunt for the food to survive Winter.
