Let me add a free npc farm in Upper Lorraine...
I just drove a guy out of his NPC farm...silly guy kept scouting me, so I had to kill him. The two flats are side by side at 14, 351. You will see you would be surrounded by your very own NPC farm.
If you have 2 towns in Lower Lorraine already, I recommend you set your third city up in Upper Lorraine. Contact me for more info on more sensitive reasons why you should have a city in UL, which I don't want to post here.
