The adult and kids' ski schools meet on the snow across the square, and beyond is the Alpine Coaster, where we bumped into George, a 14-year-old local boy with a buzz-cut and an opinion.

''Park City's a nine on a scale of 10,'' he said, digging out money for a third ride on the over-snow roller coaster that opened last season.

The coaster, Park City resort's newest family diversion, is so hot that the ride was forced to take reservations. We showed up at 2 p.m. to risk the nine-minute ride in the bobsled-shaped car, which climbs slowly up a 6,000-foot-long track and rockets down around hairpin curves at avalanche speed.

With Park City's 3,300 skiable acres, you can keep moving all day and never ski the same run twice. But if you want to ski with the little nippers, head for the slopes under the King Con and Motherlode chairlifts. Parallel runs, most intermediate but a few rated for experts, make it easy for parents and kids to split up and still meet at the bottom of the chairlift.

You can design a route to suit everyone, using the resort's newest and smartest service, the Personal Mountain Planner. This computer program creates custom routes depending on your skill level, desired terrain and a challenge quotient. The information desk in the Legacy Lodge will do it for you on site or you can do it yourself at home, at www.mymountainplanner.com. For example: ``Exit right off Bonanza lift. Take Homerun to Claimjumper. Board Silverlode lift.''

Park City resort's real claim to fame -- its link to Park City's early history -- lends a genuine sense of authenticity. Century-old structures, restored or stabilized, have been left in place on the mountain, many next to the ski runs. More than 1,200 miles of abandoned mining shafts are still there, too, a reminder that skiing's a late arrival.

DEER VALLEY RESORT

Luxury is Deer Valley's middle name, but courtesy comes closer. The resort upgrades its chairlifts regularly, improves grooming and restyles its restaurants. But it's the people that lift skiing from a sport to a culture.

At the entrance, valets took our skis and carried them up the steps. Every lift attendant made sure we sat together and safely, and handed us dropped gloves and poles. Mountain hosts offered assistance at the top. The trails were well-marked and the signs were easy to read from a distance.

Deer Valley, with 1,825 acres, is half the size of The Canyons. But the mix of beginner, intermediate and expert trails off Bald and Flagstaff mountains meant we could ski together or separately, and still meet for lunch at the Royal Street Cafe, at midmountain. With a limit of 6,500 lift tickets sold daily, there were few crowds. But the cap has nothing to do with skiing, it seems: It is the total number of seats available at noon in the resort's on-mountain restaurants.

By chance, former Olympic gold medalist Stein Eriksen, a legend at Deer Valley, happened to be at the next table. Typically gracious, he leaned over to offer a few words of welcome. Eriksen, who will be 80 this year, likes to get out and meet people, even skiing along for a few runs. Who knows? You could be lucky.
