here's a tip on how to learn the freeways/highways in la area. get a copy of the terminal chart. look on the back side where there is a vfr planning route chart for airplanes. it has all the roads you need for flying traffic/news. highlight them with colours and write down the freeway numbers (405, 5, etc). there is plenty of room to also note the reporting points you need. took me some time to prepare, but great assistance when flying. you can also put down frequencies, etc. worked for me when i flew for abc 7.
btw, tell 'tv 7' hi from finn if you get the chance to hear them in the sky. =)
