50 wines for $25, for a good cause? Count me in. Tomorrow night, at the Essex Art Center in Lawrence, Mass. local wine lovers can sample 50 different wines from different dog-friendly wineries across four continents in order to benefit Methuen’s MSPCA’s Nevins Farm. The MSPCA at Nevins Farm devotes its time to caring for small animals as well as farm animals and horses, and they also run a slew of programs including the Equine Ambulance & Rescue Training Program, a Humane Education Program featuring a Summer Camp, Hillside Acre Animal Cemetery, and MSPCA Dog Training classes, all without a dime of government funding.  Tomorrow night, guests will get the luxury of viewing art, sampling craft beers from small breweries around the country, and eating animal-friendly appetizers prepared and served by Whole Foods Market of Andover, Mass. And what’s food and drink without a little entertainment? The White Street Band, which plays an edgy, Chicago-style blues set, will be performing while you enjoy your snacks and beverages. Not a bad Friday night out (from 6-9 p.m.) for the small price tag of $25.
