what is the weather expected to be? it's early July and i just looked at today's weather it's a balmy 67 in Milw. and in Atlantis it's 91. would love to help but think the "frozen tundra" might be a tad bit chilly on the Lake Mi water. means i would need a lot of these to stay warm.
Good news, I read the lake is up 1' from last yr. hope you have another great turnout.
