Michael, last a knew one of the few remaining houses is right on the highway so if you go to the end of 14th west turn left and its just one or two buildings down, you can't miss the loading dock. Not sure about the hours though. But who knows, since last I saw it the place could have become a tanning salon or Manolo factory outlet.
The last time I was at a party on the old block was about a month ago for Funhouse which was doing one night in the old Cooler space a few doors before the Jackie Corner. It was an island of BDSM/Industrial/Goth aficianados salting down the truly weird swankies clogging the trendy restaurants and the unmentionably squeeky clubs. Designer-wear girls started coming across the street to smoke among the Funhouse crowd, you know, for a little 'soft adventure'. I just had this huge feeling of like being in the station after the train had long since departed.
