hi, Farm is the earlier spot for food, but almost any mission can have food in one of the 7 Crates afterward. the Ads for food/water is good option, and it gives u more the higher ur account lvl. Try doing Danger mission when u can, since XP/rewards available are tripled. The barricade doesn’t have to be 100%, just safely above 30%, so don’t keep too much survivors u don’t need.
