So I hear that there may be a few Harry Potter fans on this forum. I imagine many of said fans would enjoy being able to spend a couple of days in that world.
I am a UK based LARPer (or Live Action Role Player) and I've been looking into all kinds of LARPs run all over the world. Some friends of mine at Cosmic Joke did a documentary about this and they found a Harry Potter LARP run in Poland which looks all kinds of amazing. Rather than me trying to describe it watch this video
I really want to go to this at some point. it looks so awesome!
