I don't know if synthetic parties have the same security, but I never seem to have a problem at amazura when they have goa parties here. Of course I've never been to a regular party at this venue, because i think it's a little small. the psytrance community is way smaller so you get lots of room for yourself, but i can't imagine how it would be if it was packed as tightly as some of the venues in nyc (like the tunnel for one nation).
The one thing that i do hate, even at the goa parties, is that they do not let you refill your water in the bathroom. ripoff. what if you were bringing some water to a friend that's overheating and you have no money? oh well....
