Rockefeller Center Ice Skating RinkYou may not have carved your pumpkin or basted your turkey yet, but wintry pastimes have already come to New York City: The Rockefeller Center Ice Skating Rink has officially opened for the season, with other rinks to follow soon. Open from October through April, the rink first welcomed skaters on Christmas Day, 1936. At only 122 feet long and 59 feet wide, and able to hold (safely) only 150 skaters at one time, it probably packs more punch per square foot than any other ice skating rink in the world. (The rink is located between 47th and 50th Streets and 5th and 7th Avenues, in the middle of a maze of buildings. It accepts cash only; 212 332-7654.) The rink offers skate rentals and lessons, and generally charges a premium for visitors to be able to say they skated at Rockefeller Center. (The big lure, of course, is to be able to say you skated near the Christmas tree, which makes its debut early in December.) But the Rockefeller Center Ice Skating Rink isn’t the only game in town. There's Wollman Rink in Central Park, which opens this Friday, October 23, for the season, and is located mid-Central Park (212 439-6900); and Lasker Rink, located at the very north end of Central Park near 110th Street (917 492-3857); the rink is scheduled to open on October 27. With winter seemingly here already, can Memorial Day be far behind?
