GTA V: Interesting Location: Crashed Rusted Cargo Plane

Guess it didn't properly make the takeoff.

In the submarine (which I would suggest to use as half of the plane is very deep.) You can find this very old rusty cargo plane. There was an opening with a ladder to the cockpit but I could not get in there but I didn't see anything either. Some of the weapons are partially hidden so I could not confirm which one I picked up.

At this location you will find:
-Armor (in hull)
-$12,500 case (in hull)
-SMG (?)
-Full Health
-Pump Shotgun
-SMG
-Assault Rifle

GTA V: Interesting Location: Underwater Base

What they heck were they making down there?

With all the scum and villany, you should have figured at least one of them would try and make an underwater base. Well it looks like someone tried and failed. There is a large incomplete constructions site, with a large cylinder that you can go inside. There is nothing inside that I could find but there is a lot of other stuff lying around nearby.

What is there:
-MG
-Combat Shotgun
-Grenade
-Health Pack
-$25000 case (near the tube entrance on top)
-Assault Rifle
-Full Armor
-Grenade Laucher

GTA V: Interesting Location: Crashed Passenger Plane

Glad I wasn't on that flight.

This one can probably be found while picking up the nuclear waste as it is not to far from one of them.

Swimming around you can find:
-Grenades (2)
-Grenade Launcher
-SMG
-Combat MG

GTA V: Interesting Location: Crashed Cargo Plane

There are a few bad pilots out there... other than me. 

It helps if you have the submarine as you can just get out of it and directly into some scuba gear but this location has a crashed plane that looks like it has been here a little while.

You can find:
-RPG
-SMG
-$12,000 case 

GTA V: Random Event: Large White Girl Robbed

Won't they ever learn?

As Trevor moving south, a large woman wearing white yells out that she has been robbed at the ATM machine. You see a guy running away with a gun. You run him over and get $500. If you are nice, you give the money back to the woman and end up with only $50. 

GTA V: Random Event: Lost Van Steals From Clothing Store

Those lost guys sure are mean

Driving East as Trevor, you drive up just as a Lost van is driving away after stealing some money. If you persue they will open the rear doors and start shooting. If you kill all 4 of them from the Van and pick up the prize, two bikes with two guys each will come up behind you and try and finish you off. 

GTA V: Random Event: Griff the Fat Washington Patriot

He is just a patriot using his right to complain

Driving West as Trevor, you see a fat guy named Griff dressed as George Washington on the side of the road with a sign saying "This is the land of opportunity, get out!". He is very verbal on is feeling about Mexican and they are not favorable.

You can go up and talk to him if you want. You will ask him about his feelings about Canadians and he will say they are worse than Mexicans as Mexicans at least have the decency to look different than Americans. You can punch his lights out with one uppercut which will make you feel better but not yield any fruit.
