I think "they" meant SpaceX, not NASA.

Besides, you are incorrect: Atlantis just landed back in Florida, as did most of the shuttles. CA was just the backup landing site, and they often waited a day for weather in Florida to be good rather than land in CA to avoid the hassle of transporting the shuttle cross-country.

Check your history. California Edwards AFB was the backup landing site but became the primary landing site for most of the early years of the program. A runway was built and maintained in Florida but never used until the 90s.

According to wikipedia, http://en.wikipedia.org/wiki/Shuttle_Landing_Facility, the runway was too good at its job and ended up breaking landing gear. So they spent 6 years sanding it down. But when I was a kid and asked why they landed all the way over there, someone at NASA told me it was the unpredictable Florida weather.
