In a Brotherhood mission called Jailbait there are three buses you have destroy,
Do not destroy the buses try to stop one of them and steal it,then quit the mission.

Enter 5556677 ,Hazmat on your phone anywhere and one will come by, steal it.It is simallar to the Septic Truck.

Well, they don't give it to you so on the last samdei mission; the shopping maul. So you gotta fail the mission while in the limo, and dieing wont do ya any good so heres how I did it: when the general and the unimportant samdei members arrive at the mall, kill shaundi or just get in the limo and leave her, and when you fail the mission, exit the mission and you should still be in the limo, ull notice there is no radio, and no noise at all coming from the car, that will fix when you put it in the garage, you can't mod it, but it's still pretty friggin cool.

This is a farout easter egg really you start at the prisons north side head west on a boat and only a boat youll see som small islands in the distance when you get to the one with the water fall and the violatin shrine get on the side with the arch go north north east youll find a small ruin with som stairs go up them and a arrow will appear follow in the way it's pointing till you find the next island go on it find the next arrow beside the one and only tree then go the way it points till you find the next small island drive slow and look carefully for it it's a small island and easy to miss then when you find it follow it's arrow in the way it pints then yet again drive slow ad look around for the small island in the foggy distanse and when you get there get on top of it and it will vanish and youll fall into the water with a bunch on arrows all pointing in the same way look that way and youll se a giant pink bunny rise from the ocean holding eggs or marshmellows I'm not sure which they are and youve just seen one of the many secrets of stilwater :)

Its easier to find the island if you put in the cheat 78669 to make it sunny and 1200 to make it noon enjoy it :)

Peace of mind may you all find my groovy friends
