And how do you get to one of the other islands?

there are 2 NRG-500 the first island on east coast in a car park trust me! I have two of
them!

When u unlock Las Venturas u go to it there should be a red $ in the southwest reigon

It is in the Easter Basin Docks In San Fierro. It is at the ring

Go to the san fiero airport, and where the 2 big open hangars are, look across. Youll see
4 hangars. Go in between the 1 and 2 hangar (starting left) and there should be one there.
If not, go for a drive or somthin and come back.

BTW, those 4 hangars are all closed unlike the 2 bigger ones. And are located near the
rock cliffs.

I wnt 2 san fierro and found that bike at the docks where the empty watered area where the
boats come in it's under da crane
