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.
Vail is barely even a real city. I don't think there's even a typical grocery store (or dispensary for that matter) within the city limits. It's mostly just an amalgamation of hotels and storefronts with the facade of a European city for rich people to have "mountain getaways" while they're within spitting distance of the interstate.
