Reader Travis B. recommended the blog Laptop and Rifle [4]. Travis gave quick summary of the blog’s content: A guy that used to work for Google (a smart guy) buys vacant land and blogs his experiences living there full time.

It might make a good case study or would generate interesting responses from your readers.”
