Moving to LA

I'm four days out from moving to LA. I want to start a garden at the new place and my father was telling me to make sure no one outside can see it. He's worried that people would try to break in to get food. However I know that I can only put plants in the back of the parking lot and that I would have to make raised beds AND that if I put up a screen my plants might not get enough sunlight. I'm really looking forward to eating my own produce as well as sharing it with others.
