It's always been an interest of mine to go to an authentic warehouse rave. However I don't know that I was born in the right decade for it or that I've ever known the rave-going person. Do they even still happen anymore? You know, the kind where you make three different stops to get directions to the actual place.
Here's an account of one I was at with ecib and cgod that got busted.

They came flying in with guns drawn. My buddy said he walked out of the bathroom to a pistol in his chest.
That police officer that said "Don't you have parties in my city anymore. This is my city. And I won't have this any more in my city" was actually Gil Hill, of Beverly Hills Cop fame.
As I was on my knees with my hands behind my head, I saw a cop's badge laying on the floor. I still regret not picking it up. But, i didn't know if I'd be searched.
We went to a Denny's after that and showed some cops our tickets. They said something like "Were you at a brothel?" The Detroit Police dropped the charges against all of us.
Good times. I am sure they still happen.
EDIT: one of my favorite tracks from those days:
