The best way to find one in Fullerton is to call the city clerk (308-536-2428). You might have bigger luck in Central City (20 miles south) or Albion (20 miles north), their newspapers are not online but here are their city clerk #'s
Central City-308-946-3806
Albion- 402-395-2428

You may also find this interesting, as Central City and Fullerton have free lot programs. I don't know how successful they have been, but they are made to encourage people to move there. Kenesaw, a town near Hastings, has had good luck with thiers. Anyway here are those links:
