GTA V: Random Events

Grand Theft Auto 5 has many random events throughout the map. Some funny, some profitable, all entertaining. I am honestly not sure if you need to be certain people to get the certain events but I have marked them down as such just in case. Trevor also has a unique issue of looking for hitchhikers that he can then send to the altruist cult for profit instead of their intended destination.

It is quite possible to get these events with different people but these are the ones that I found them with.

Trevor:
RV Sex Interruption
Large White Girl Robbed
Chase Thieves Country 2
Griff the Fat Washington Patriot

Trevor Hitchhikers:
Hitch Lift 3
Crash Rescue (New Heist Driver)
Burial ($60,000)
Hitch Lift 2 (Ursula New Contact)

Michael:
Bad Bikers

Franklin:
Deal Gone Wrong

Rogue Altruists 
Domestic  (New Golf Partner)

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
