Our weather is no secret -- sun, sun, sun -- and our kids are used to it. Which is why they have a wardrobe consisting of shorts and cotton T-shirts rather than corduroy pants and wool sweaters. But Magic City munchkins can still get a cold-weather chill if they head up to North Miami and the only regulation-size ice-skating rink in town. Chances are it'll be a new experience for them, but with role models like Miami Olympian Jennifer Rodriguez, who made the switch from Rollerblades to ice skates, they may already be gung-ho. The arena staff offers lessons (group and individual) for all levels, from beginners to budding figure-skating stars. Hockey lessons too. And hockey leagues. And rental skates. And infrequent but regular free skating. And some of the coldest air conditioning in the subtropics on a hot and muggy summer afternoon. Call for rates and hours of operation.
