Spring brings out the nostalgia fiend in me; the part that firmly believes Haggadas should hail Maxwell House and kids should hunt for the afikomen between plastic-covered couch cushions.

Yes, I romanticize the past — particularly the 1950s New York, kreplach-canasta-Catskills Jewish past, which I missed by a couple of decades and several states, growing up as I did in 1970s Chicago suburbia. I moved to New York hoping that somehow, despite the odds against me, I, too, could become a Dodgers-loving, brisket-braising, Coney Island-bathing Jewess. Maybe a little Yiddish could work its way into my conversations, nu?

No. It was all too self-conscious. For 20 years, Marjorie Morningstar's era fox-trotted farther and farther away. There was no goose-shaped chopped liver for me. I was doomed to live in the blueberry-bagel present. After I had kids, I accepted the fact that every year around this time I'd be attending parent orientations for "Computers 'n' Karate Camp." That is, until I discovered the Jewish answer to Brigadoon:

The bungalow colony.

What's a bungalow colony? That's what I wanted to know when my friend Carol invited my family to visit her up in Monroe, N.Y., a few summers back. Like many New Yorkers, Carol grew up going to bungalow colonies and chuckled at our ignorance (my husband is from Chicago, too). "You've never been to a bungalow colony?" she asked. "Just come. You'll love it."

She neglected to add, "And once you do, your life will be changed forever."

So we rented a car and drove up Route 17, passed a barnlike restaurant called the Red Apple Rest, and a few miles in as we trudged in from the parking lot — parking dirt, anyway — my husband and I literally did a double take. The place looked like it came straight out of a Norman Rockwell painting — if Rockwell had been born Normy Rosensweig: A hundred whitewashed cottages sat shtetl-close to each other and a big swath of grass ran down the middle. Clusters of ladies sat on mismatched lawn chairs discussing — yes! — last night's canasta game. The men were smoking cigars. And the kids! Kids were zooming all over the place, banging screen doors, shouting, running around in packs. Carol's children seized ours and immediately started showing them around: "This is our swing" (hanging from a tree, no less!). "This is our picnic table. This is the pool. This is the concession stand where we get candy." (What, no charlotte russe?)

My kids disappeared down the path and Carol insisted we sit tight. They were safe here. No cars. No strangers. By age 3 or 4, children start wandering off with their friends, Carol told us, and ours just had. The only rule for grown-ups is that if the pack ends up at your bungalow during lunchtime, you have to feed all of them. That was the reason Carol had such a huge tub of peanut butter — and a freezer full of ice-cream sandwiches.

The rest of the day was spent in a daze of pleasure and disbelief, mixed with more than a dollop of envy: You mean you've been coming here for years? (Yes.) And anyone can join? (Of course.) You don't have to know someone? (Don't be ridiculous.) But does everyone already know each other and would we be out of place? (No!) Does it cost a ton of money? (About $4,000 for the summer.) What do you do with the kids all day? (This particular colony — Rosmarins — has a day camp, which Carol actually had attended as a kid, darn her!)

Okay, so: Who are all these people? Teachers, Carol said, plus a small cadre of her friends from Manhattan and a whole lot of older people who had drifted here over the years as their colonies closed.

Because that's the sad truth, we learned: Of the hundreds of bungalow colonies that once thrived throughout the Catskills, most are dead or very different now, killed off by the three A's — air-conditioning, airplanes and assimilation. Once people could stay cool in their homes or fly someplace fancier for the summer, they did. Moreover, once Jews no longer felt compelled to cluster, they didn't.

Some of the colonies that managed to survive became exclusively Hasidic. Others were revived by Russian Jewish immigrants. But very few colonies besides the one we were visiting continue to exist the way they did in say, 1955, when a summer bungalow was the height of middle-class Jewish pleasure — and no one had heard of computers, much less computer camp.

What more can I tell you? Here was the chance I'd literally been dreaming of — the chance not only to step back in time, but also to take my family with me. We made our deposit a few days after that first visit and this summer will be our fifth at the colony. Every year we rent the same bungalow and every year our kids look forward to a summer that they think of as normal, not some strange time warp. They don't know that in that great Jewish tradition we're giving them the very joys we were deprived of as suburban '70s children: A cramped little cabin. Neighbors so close you can hear them on the phone. Minimal supervision and a smattering of Yiddish.

The only thing missing? A goose-shaped chopped liver. But this Fourth of July — who knows, nu?
