if your powerful enough.... go to redding, kill the aliens (90hp each) and then craft as much as you want as redding has a workbench right next to the mine elevator and the mine itself is in the town, otherwise its eighter junktown, ncr or gecko (i dont recomend gecko as CS usually kills miners there to loot your ore, be aware that they have scouts that look like miners who call the PKers like hubertus and others) San fran is deadly yea.... modoc and that area is also viable for crafting but has limitations of no electonic parts and no junk nearby (also unguarded towns)
