Some enterprising folks on Airbnb are offering an opportunity to camp in a glamorous Oshkosh, WI “ice cave.” The ad brought to mind Andy Gratton’s recent visit to Lake Christina in Minnesota, where he sailed his new blue Renegade. Andy did something he said he always wanted to do; he pitched his tent and slept on the ice. Thanks, Andy, for being a good sport and letting me have some fun with this parody ad.
