Where in Southern Cali can I get a mosquito net/ screen room?

Question:like for eating in? its kind of like an EZ up, but it has screening on all four sides

Answers:
I believe you can get them at most places that sell tents and camping equipment. Have you looked at Sears, K-Mart, Wal-Mart? Do you have a Gander Mountain or Cabelas store near you? That would be my best offering for an answer.
