Another update time.
A few of my friends went today as they had heard it was open again. Got in fine and got a few shots but then it went very badly.
A group of two men and one woman turned up, went inside, ripped their camera gear out of their hands and then proceeded to try and instigate a fight once they had managed to get outside, they got most of the gear back except a tripod, apparently one of the group who arrived had 'lobbed it' and so he's lost it now.
Totally insane behaviour from people who were apparently keyholders/security or whoever they claimed to be, so I'd say this is one you definitely want to avoid like the plague or maybe feed it to goons you don't particularly like or care about and get them to park out front.
