Seed: SpankoHome.
This seed is awesome and I have barely explored it. There are 2 hub cities close to each other. At least 6 other towns in good biomes. There is a solo and prison. At least 2 traders. The awesome thing of all is there is a large army barracks the one with the concrete walls and at least 5 large bunkers 2 out on gravel roads and several small bunkers. There is at least 2 forge houses. 2 cross roads one with a hotel. A motel and a factory.
This map seems to have 1 of each POI. Only one area of wasteland so far and lots of water that is easily navigated.
I am on day 26 and I have yet to find a permanent base because there are so many awesome options.
