Which parts of Jewishness are you proud of? Just a general "yup, that's my genetics"? Or in various achievements? Can you tell your children of the achievements attained by individuals, rather than with the help of God? (BTW, I'd say if it's in the holy texts, it's with the help of God.)

Is it the culture you like? Can you find the bagel bars or something like that? (Sorry if I sound a bit trite, not intended.) Can your children get to know the people, culture and music without the temple?

Good luck with whatever it is you want your children to learn about!
