Yeah I never bought a beer once, I got so many cans in. \o/
To be fair last year was even sillier. The rule was simply "no cans", so everybody just decanted booze into bottles, which they didn't bat an eyelid to. There was also a complete lack of bag checking, as said, which always feels like I've wasted time moving stuff out of glass bottles.
I saw the smoke bombs, but I didn't realise there were flares too. Proper ones? At Glastonbury there were some seriously strong ones, that you couldn't actually look at. Someone even had an actual flare gun, which was just plain awesome.
