Stay at home spouse is definitely more common in the Midwest, and I imagine that's what my family will end up being.
My wife and I went to California for two weeks last summer. Did the whole Highway 1 crawl. San Diego, LA, Big Sur, SFO, Wine country. Thank Jesus for frequent flyer miles and Priceline. Honestly loved it, except for most of LA (excepting Santa Monica which was amazing). Although your late June summer nights were a bit chilly.
What I love about the Midwest is baring a catastrophic job loss, I've already won the game. It's just so cheap. I have an updated 3/2 house in a top school district in walking distance to Whole Foods, restaurants, library. Student loans will be paid off by ~33. We have extra money to travel all the time, especially with my knowledge of the credit card miles game and Priceline. The only negative here is the winter, December - March is pretty meh. But I honestly, completely cannot imagine living somewhere where owning an average house is unreachable, where I'd spend all of my money on rent and have no money to jetset around the world. I've looked up how much a 3/2 house costs in Santa Monica. It's 5-10 times (or more) as much as my house.
