As if the winter chill isn’t enough. Some folks in Holden are going swimming Saturday outdoors.It’s the annual Freezin’ for a Reason Polar Dip.Folks will plunge into Phillips Lake to benefit Camp CaPella and Camp Sunshine.Before taking a jump in the icy waters, it’s always good to have a plan.”Wear waterproof boots until it’s time for you to jump in. Wear as little clothing as you can because you don’t want to hold the water on you, get in, get out, and get in the hot tub, and get warmed up, and have some hot chocolate,” said Joe Dowling, of the Hampden Kiwanis Club.”Well, we have a great time down here, and it’s a great spectator sport as well. What this is about, this is about sending kids with disabilities and kids with life threatening illness, to give them an adventure of a lifetime by being able to come to camp. So, this is what it’s all about,” said Dana Mosher, the executive director of Camp CaPella.Registration begins at noon. Plunges start at 1.Shuttles will be running from Lucerne Inn and Dedham School starting at 11:30.For more information, or to donate, you can click on crowdrise.com/bangorpolardi[.
