If you get to the UK in May definitely come to us first. There's a massive festival on here for the whole of May (second only in size to Edinburgh) that would be a gold mine for your articles. Look it up on the internet it's on every year.
We've been to some really wacky brilliant shows just because we happened to be walking past. We go mostly to Fringe stuff.
Then there's loads of stuff in the streets and Open Houses which are great fun.
