The free party scene in North Wales is virtually dead.

A couple of years ago where crews from England picked a venue badly which was a holiday visitors spot (thus frightening away tourists and their money); it ended up with a nasty brawl between inexperienced cops and angry ravers at which a cop was blinded in one eye by a thrown rock and ravers were hit with batons.

A load of people from my former area got caught up in this event and many had to prove to cops they had not been involved in the incident where the officer was injured (they had to keep going back to Wales every few months for bail etc)

They got away only with fines for being involved with the event and had their sound equipment and vehicles returned; but the cops are determined never to let another illegal rave happen in North Wales.

NW England appears to be a different situation though 😉
