@por500bolos I'm not old enough to have attended Woodstock but this week is the 28th anniversary of a free festival and rave at a place called Castlemorton in the UK. it was a few days of anarchy and madness organised by a small convoy of new age travellers pulling on to the site on the Tuesday having been moved on from various places and by the Saturday there were between 40,000 and 80,000 people there (estimates vary wildly but I'd go with the upper end. Bear in mind there was no promotion beforehand, social media hadn't been born very very few and mobile phones. 1 answering machine message and word of mouth was all it took.
It was a mad and incredible few days partying at all of the various stages and with little to no trouble, sanitisation was the biggest issue. I did hear of a guy ripping people off who was dealt with on site and packed off on his way.
Unfortunately the festival caused a huge fuss in government which led to the criminal justice bill, a law specifically targeting gatherings and music "wholly containing a succession of repetitive beats" a law against a music genre.
Things changed, business got involved and we are where are now.
It was fun while it lasted though!
