Best American city to live a bohemian lifestyle

I've made quite a lot of money in my work but I have no desire to continue working a 9-5. I currently live in an expensive east coast city, but I'm looking to settle down in a city with a lower cost of living, adopt a modest lifestyle, and focus on the creation and consumption of art until I run out of money.

Key factors:

• Low cost of living
• Cultural amenities

• Somewhat educated populace

  Secondary factors:

• Walkability (at least in a core area)

• Dating options for a mid-thirties man (I'm not holding my breath though)

Thanks.
