Oh, there is a town! Can't remember the name though, will check it out on my map.
Super mutans keep all sorts of meats in their bloodsacs and always seem to have tons of ammo too.
Yao Gaui seem to be less abundant in FO4 than they were in FO3 .
Though I've at best only covered 1/3 of the map in general.
Seems so far the best source of that meat is off random trades or stumbling across super mutant blood sack stashes.
A pack of them attacked my Drive-In settlement.
I had a pack of ghouls. Was pretty cool looked like the zombies were coming. they started far off and slowly shambled over until i opened fire and they started running at me.
