Spent a couple days on the ice of Lake Hopatcong in New Jersey in 2022 documenting my Dad and his pals in the Lake Hopatcong Ice Yacht Club. A great group of characters that gets together whenever the ice gets thick and smooth enough to sail on. 

Speeds up to 70mph on ice in a boats ranging from nailed together pieces of wood to high performance carbon fiber hulls. I will admit I don't know much about the sport but these guy's enthusiasm for it is contagious.
