That's a good question.
There's the natural order (rural life, self-sufficiency, classical education, your family's values -- not to be confused with morals -- culture/ethnicity, etc) and those things are good in themselves, and each is worthy of putting in a certain degree of effort to pass on, as much as possible.
But, of course, none of them are important enough to give up the Faith for.
It's also true, though, that having a sane life on the NATURAL order (rural living, for example) is more conducive to piety and virtue than, say, living outside Washington DC and commuting to work in heavy traffic everyday, in order to push paperwork in a big office all day. Being surrounded by skyscrapers (even smaller buildings) all day every day makes you emphasize MAN and MAN's WORKS in your thinking.
When you're in the country, you are more affected by the weather (rain, shine, drought, flood, etc.) and you realize how much you're at God's mercy. It puts you in a more proper position of creature in relation to the Creator.
I'm sure there are a few good big-city Catholics out there, who play sermons in their car during their daily commute, etc. but I can't help but think that in going against the grain they have to be the exception.
What to do?
Yes, I'd probably put in a small effort to find like-minded families. I'd emphasize to your children how important the Faith is above all else. You don't want them getting the wrong priorities and dating men because they're more attractive, have certain natural virtues, etc. even though they're not solid Catholics (and Catholicism is inherently Traditional, so I guess I'd have to say Traditional Catholic)
Is the SSPX still hosting that Young Adults Gathering? I've never been to it, but I've heard of it. It used to take place in Colorado. It's supposed to be a way for Catholic singles to have good clean fun together and -- you never know, maybe meet their future spouse. I know of other trads who have gone "spouse hunting" in places like Post Falls, ID or St. Marys, KS.
Of course, finding a spouse is only 1/2 the battle. For men, you have to find a place in the world (a way to earn a living) as well -- that's at least AS hard as finding that spouse.
It behooves Catholic children today to waste no time -- get a solid foundation in virtue, especially hard work, and develop some skills as children, rather than wasting so many years in the late teens "having fun" instead of being serious about life.
