If you live in LA you'll need to go over at least one highway.
Edit: ITT many Americans telling me of how walkable and great their towns are. I'm happy for you but comrades, I've been to the US once and that was on a trip I won in high school so don't expect me to know the zoning plan of Providence, Wisconsin Pop. 235'489. I don't really care how lovely your city with two buslines is. For every Seattle or Chicago there are 34 Cincinnatis, Houstons and Las Vagases and approx. 234 exurbs and suburbs.
Portland is (Nazis aside) so much better than Seattle urban planning wise. Like, there's something special about being able to bike everywhere without climbing 500 feet. Plus, the extra 20 minutes of sunlight are the chef's kiss.
