Get out there. Yes, we know it’s cold. But get out there. Warm up and sweat off those extra pounds from the holidays.

Go snowboarding. If you know nothing about it, check out the equipment demos at Mountain Creek resort (www.mountaincreek.com) in Vernon, Sunday 8 a.m.-5 p.m.

Go cross-country skiing. The New Jersey Audubon Society’s (www.njaudubon.org) Weis Ecology Center in Ringwood is sponsoring beginner’s clinics Saturday and Sunday. It’s $5 members and $10 nonmembers if you bring equipment, or $15 members and $20 nonmembers to rent gear.  Times depend on weather, so call (973) 835-2160 to find out. Saturday 1:30 to 3:00 p.m. there’s a bird feeder workshop, where you learn to attract different kinds of bids to your backyard.
 
Go birding. A bracing walk on the beach or a hike in the woods might yield some wintering rarities (www.njaudubon.org/Sightings). If you need an expert to tell you what you are seeing, nature guides from the Cape May Bird Observatory (www.birdcapemay.org) take groups on walks through the best seasonal habitat Saturday mornings.

Say Hello Kitty at the Central Jersey Cat Fanciers’s show. Bengals, Sphynx, Maine Coons, Siamese, Orientals, Ragdolls, Persians will be there — and also homeless pets for adoption. Admission $7, Sheraton in Iselin, Sunday 9 a.m. to 4 p.m. (570) 807-0406  for more information
 
Sunday is Three Kings Day in Latin America and Mediterranean Europe, when children get gifts to commemorate the Magi said to have visited baby Jesus bearing gold, frankincense and myrrh. The Kings, Melchor, Gaspar and Baltazar, will be in full royal regalia Saturday 1 p.m. at the Camden Children's Garden (www.camdenchildrensgarden.org). Then at 2 p.m. ¡Retumba! — “a multi-ethnic, all-female ensemble dedicated to the folkloric culture of Latin-European and Afro-Caribbean cultures” — celebrates the holiday at NJPAC (www.njpac.com). $20-$22. 

But the hottest ticket this Enn-Jay winter weekend is for Hannah Montana Saturday at Boardwalk Hall (www.boardwalkhall.com) in Atlantic City. If you have been living in a teenage-less cave lately, we can tell you it’s a spinoff concert from the hit Disney Channel series (http://tv.disney.go.com/disneychannel/hannahmontana) starring Miley Cyrus. The show is sold out, but tickets were still available from Internet resellers this week for as much as $2200.

We won’t say if that steams us up, or leaves us cold.
