You people are very lucky to have goa parties...or what us Americans call "raves". They would usually start about 10:00pm and last until 5:00am to 6:00am in the morning. It was the same scenario, lots of people, lots of goa, lots of acid . Those were some very great days, but then the police started raiding them because of the drug use. As of recent, raves are very hard to find in the USA...and the ones that do come up usually have a $30+ cover charge. I havent been to one in almost 6 years .
