Jim Dreyer plans 22-mile swim towing 250 cannonballs in August

Jim Dreyer, a 62-year-old long-distance swimmer known as "The Shark," is set to tow 250 cannonballs while swimming 22 miles on August 7. This event is part of the White Lake Maritime Festival in Whitehall, Michigan, intended to commemorate America's 250th birthday and raise awareness about preventable veteran suicides. Each cannonball, weighing approximately six pounds, contributes to a total load of about 1,500 pounds, with one cannonball symbolizing Dreyer's late father, a World War II veteran. Dreyer is undertaking this challenge after previous attempts to recreate his Lake Michigan swim were unsuccessful.
