I have Abernathy Farm and Country Crossing as my main food suppliers, Warwick Homestead as my water purification source and as a small shanty town, and The Castle as a military staging ground (draws in lots of settlers, which I then equip and distribute to unprotected minor settlements). Most other settlements are slave camps with lots of scavenging stations set for junk collection (supply lines are very useful). I might send pictures at some point.
