Rednecks
Rednecks are a bunch of people in Crater Rim who live in trailers or trailer-looking structures. Their culture seems to be more or less about drinking moonshine and talking like stereotypical rednecks.
Interacting with Rednecks
Rednecks aren't always hostile to outsiders, so you shouldn't be too afraid to move amongst them. Rednecks are armed with a variety of weapons. Even though some of them may have something as menacing as a chainsaw, they are not very skilled with their weapons. They're not a very big threat, but you shouldn't take them on too soon. The most notable thing you can do with them is killing them and getting their moonshine for the moonshiner job. You can also get a Freedom City Enforcer contract and kill them for money.
Getting to Rednecks
The easiest way to get to them is to use an osprey or a huey. Just go over to AP roof and activate the beacon, enter the vehicle and then just tell the driver you're going to Crater Rim. You'll arrive in no time. You can find the rednecks east from the Crater Rim helipad..
