Let's deal with Salt Lake Park, the stolen cows and the town of Rodia before we go any further.
Wasteland 2: the first L.A. side quests
Side Quest: Salt Lake Park
Head towards the marker when you get the distress call about a farm being attacked by mutants. Follow the path of dead crows and go past the fence around the house until you come up against the creatures.
They have 20 HP each dso they're pretty tough. Once you've defeated them grab one of the animal parts and go back to the gate in the fence. The man here won't let you in but you can trade with him to access, so show him the animal part rather than any proper loot.
Now it's clear of mutants go back towards the World Map and you'll encounter a group of robots. Kill them and continue into the wasteland. Head north of Salt Lake Park on the World Map and you'll hit a level 5 radiation wall. Woodson will now call you next time you enter a new instance.
Side Quest: Retrieve The Woman’s Stolen Cows
You'll get a call to help a settlement south of the Ranger's Base. Head towards Cerritos and speak to the woman to learn that cyborgs stole her cows. Continue past her until you see a corpse. Examine it and pick up anything there is to take.
As you head towards the cyborgs you'll see conversation bubbles pop up - tell them you're a Ranger and you'll start a battle If you kill them all the cows will return automatically. Talk to the old woman again and she'll offer you the rifle which you can either give to your team or sell off.
Side Quest: The Town of Rodia Needs Your Help
Woodson will call and ask you to return to Sante Fe to meet a visitor. speak to Pistol Pete (he's standing next to Woodson) - he's a travelling merchant. He will ask you to help his town, currently overrun with bandits. Accept his help and let him come with you and head out to deal with the issue.
Go towards Rodia and enter the instance where you will see a cutscene. Talk to the large pink bandit and she'll ask you for 6 bullets each to pass. Say no and start a fight.
You'll now need to use Lockpicking on the entrance to get access to the rest of the town. Kill the enemies just inside the walls and take down the two guards near the gate blocking the radio towers. you'll need to fight a few more bandits before bringing the cage down which contains the poor old mayor.
You'll need to fight one more group of bandits before you've saved Rodia and complete the quest. If you have a spare Repeater Unit you can use Mechanical Repair to fix the radio towers here.
Go out the gate until you see Pistol Pete, talk to him, then go to the mayors office (inside his house) and he'll ask you to deliver a message to Mr Manners in Angel Oracle.
