'Hollywood' in general is like this. All the film studios have real life people working in them and who have lives outside of their work. One of the reasons that Bel-Air, Beverly Hills, Malibu, etc. are what they have become is that they are a commutable distance to the studio lots. The same is then true of shooting locations in southern CA. The ability to go back home on the weekends/evenings (in the least) is very attractive as a shooting locale.

Apparently the pay is also different if you're within the 30-mile zone: https://en.wikipedia.org/wiki/Studio_zone

[Also, my original comment should have said "southeast" not "southwest", d'oh]
