The Polar Plunge was a huge anti-polio fundraising success, but the Rotary Club of Marblehead Harbor is taking it one... toe further with the Big Toe Plunge.In a joint activity with Marblehead's InterAct, intrepid volunteers will dip their big toe at famed Devereux Beach, Saturday, March 23rd, at 10:00am. All District Rotarians are invited to participate and test their mettle against the mean surf of a (hopefully) balmy Spring day. Creative outfits and outlandish toe dipping will be encouraged. An anti-polio fundraiser will take place on location.
