If you are of a certain age, and hung out with a certain clique in high school, you might remember a rock group you have most likely not thought about for years: Grand Funk Railroad (www.grandfunkrailroad.com).

They are still an American band, and they are getting closer to your home, specially if you live near Morristown. GFR is in concert at the Mayo Center for the Performing Arts on South St., tonight at 8 p.m. Grab tickets online at www.mayoarts.org.

Horse lovers might enjoy the winter clinic on equine behavior, Sunday 9-11 a.m. at Watchung Stables in Mountainside (www.ucnj.org/parks/stable.html).

Maybe you just want to dive in, or at least watch them dive in. It’s the Polar Bear Plunge (www.njpolarplunge.sonj.org) into the frigid Atlantic, Saturday 1-3 p.m. in Cape May to benefit  the more than 16,000 athletes of Special Olympics New Jersey. Miss it, and there’s another one in Seaside Heights February 23.

But if you do make it to Cape May this Saturday, follow the hop into the cold by warming up with a nice glass of grape libation from the Cape May Winery (www.capemaywinery.com). They’re giving visitors a cellar tour and tasting.  It all starts at 3 p.m., just in time to cross over from the beach into the vineyard.

Ahh. If you are like us, by now you are thinking, “summer…the Shore…vacation.”

Start dreaming at the Wetlands Institute in Stone Harbor, which is throwing an Indoor Beach Party where you can practice the stuff you like to do out on your favorite spot of sand, whether it’s our beloved Shore or beaches of the Caribbean or Hawaii. There will be indoor surfing, kite making, hanging out in flip-flops if you like,  plus a limbo contest and, we are told, “grass skirts for hula dancing.”

You can start planning a vacation, too — a mobile one — at the 40th Annual New Jersey RV & Camping Show (www.macevents.com). It’s at the Convention & Expo Center in Edison, Friday through Sunday. You can chill inside and get a taste of the great outdoors.
