The vibe is uber rich bohemian, sure. Everything is relative -- to most outsiders SB proper is itself richie riches, it is literally 20-30 min walk fron SB coastal road to Montecito. I don't mind taking advantage of the nice "bohemenian" shops when I'm there but have you noticed how many emptied out shops there were on state street the past year? It definately gives me "Let me open my dream antique/clothing store using my family/partner's money and ride it out as far as our budget allows" vibes.

Also, compared to Europe the ocean is objectively garbage for swimming (no shade for the surfing or what not). But there is little alternative in the entire US I guess so there's that.

(not the one that downvoted you by the way)
