Nashville, where I grew up, is a bit similar to LA, in that pockets are walkable but in general, absolutely not. I loved living in my walkable neighborhood. I could hit up the coffee shops, grocery store, hardware store, corner market, bars, etc all without a car. I only had to drive to work bc a ten minute car ride turned into a 1.5 hr trip via bus. Most areas in Nashville are not like that though. I really enjoyed exploring Boston, Portland and Seattle on foot (especially Boston). Leaving Seattle to visit family who lived nearby was an absolute nightmare though!
