Answer 1

Go to Shorside Vale , & in the airport, then hijack the dodo plane
& fly to the green mountains,& fly above of them, then the screen
will reverse & you can see a grey ground under yourself, land
on it & here's the creepy ghost town, with no people!!
(It looks like Silent Hill, no?? There's also one in Vice city!)
