I like these choices. Me, I'd probably build Obi-Wan's hermit hut on Tatooine.Outdoor set, a western town.
Indoor set, Star Trek TOS.
If you had 2-3 acres of land in your backyard and you could build anything (within reason, such as you can't build the entire Death Star), what movie set would you build.
For me it would be the Hill Valley 2015 Town Square.
