Alas, I'll miss it this year as I'm moving house to Scotland. I went last year on just a day ticket and it was interesting enough just for a look-round. I was going to go for the whole weekend this year but timings for house move have messed that up.
If you can't make it to the Bush Moot then go to this instead. If you're not sure about things, just go for a day and make your mind up whether you want to stay longer next year.
