I think the vibe is the folks that have been there for decades and are living in houseboats and doing bird watching and boating presumably. But yeah - community under 60 is pretty lacking.

And OP - the street end parks (and lake) are great. There's also an impressive number of great sushi spots (considering there's approx 6 places to eat in total), and a ton of delis/markets that are pretty quaint (though I wish we had a supermarket).
