Swim to Mackinac Island for Kids

I am trying to raise funds to benefit disadvantaged
K-12 kids with Education and After School programs.
To raise awareness for this cause, I am joining a team of 2 other swimmers who will be tethered by their feet to tow a 52' diving boat containing a professional piano playing blues musician
and all support staff and gear 5 miles across
The Strait of Mackinac from the Upper Peninsula
of Michigan over to Mackinac Island.
