Okay, first you must go to the safe house in Prickle Pine (Las Venturas). Im quite suprised that not everyone knows about this, its not that hard to find. You can walk through the buildings and stuff too, its pretty weird. It resembles the ghetto in Los Santos a little bit, but it was clearly never used in the game. It will take you to a deserted town thats floating in the sky, Its pretty much always night time, and The size of this place is a couple of blocks. This is the oddest thing I stumbled upon in the game.
