Yeah sorry 2pacalypse, its kind of hard to explain where it is unless you've played GTA 3. If I said it was at the north side of the island, sorry I got confused. As u go around the south end of the island, you should see the payphone ringing - it's down this street. Just keep looking on the same side as the payphone, and you should find a concrete ramp leading down to a tall red garage. Sorry for the late reply, I've been busy playing this game lol.
