REWARDS - Respect, Caligula missions unlock
Get a four-door vehicle and head to the blip on the radar. Park in the red marker when you get there. You'll find Paul and Maccar on the ground. Get in the car (this is why you need the four door) and head to the blip on the radar to a snake farm. After a cutscene, the hicks will start firing on Paul and Macca.
Quickly take them out before either one dies, then get back into the car and head to Caligula Casino. Park in the red marker and watch the ensuing cutscene. CJ will call Woozie upon exiting the casino and say he knows a way to check out Caligula's Casino an easy way.
