It rained right at the end when Carl Cox came on and it was actually pretty cool when that happened. I’ve had some good times there, been a couple of years in a row including last year and I have nothing bad to say about it at all.
It’s a good day out on the Common, you don’t get that many events like it around London that you can go to for a day (‘cept maybe Lovebox) so if you’re in London for bank holiday and want to do something I’d recommend it.
