Off of Red Hill there is an ibusinessl park where you can shoot through the fence. It's hidden among the bushes but there is a small cut out that gives you access. You will be able to get aircraft lining up and starting their takeoff roll.
In the same area there is a very small mound of grass that will let you catch arrivals on short final but is made challenging by the high bushes.
You can see the business park on goolge maps just opposite the main terminal basically from the 405 to the start of the runway.
Oh, it's a big pretty white plane with red stripes, curtains in the windows and wheels and it looks like a big Tylenol.
I've done some decent shooting from the Red Hill Av. overpass over Interstate 405. Most of the bridge has fence along it, but if the north and south ends offer a view of approaching aircraft provided you've brought a telephoto lens. Note that the light will not work until the afternoon.
