Beating-off while laying a duker.

What'd you get up to last night?

Not much. I drank a box of wine and then stayed up masterpooing after my girlfriend went to sleep. You?

Same thing.

The greatest and largest weekly rave venue ever to hit Los Angeles in the late 90's thru 2001 venue in San Bernadino, CA. With 3 areas in Trance, Hardcore, and Drum N Bass. This venue was large enough to accomadate 3-4000 people weekly for over 20 months strong. If ever there was a rave venue that could pack week after week regarless of the show, it was The Masterdome. Long live... masterdome matt,
