I talked to Pete in the Hub.
He sends me to the NCR. I talk to the guy running Igana Bobs. It turns out the guy running it Mike.
Mike sends me to the Rawhide to talk to the Super Mutant.
Drunk Super Mutant tells me that he can be found south in a place that starts with "New."
So I go to New Adytum and talk to everyone there. Big fat nothing.
The wiki is no help and I asked around in the game, so I came here.
Where is Iguana Pete's Missing Son?
