Desert ideas?

I'd like area 51. Be better than that mars thingy that cost me 200 sardines. Thing is already in storage, cuz, my casino's took up all the new plots of land. I need a new stretch of land, to work on a desert oasis.

I turned my whole Heights area into a mini Nevada/New Mexico area. One side has the casinos with a monorail going around and the other has the Mars thing with the NARA base set back from the main area to imply it's secret or hidden or hard to reach (obviously it's not though..). I've got a space left over for whatever that update brings.
