About 12 years ago a couple of people caught (but weren't able to get into the boat, nor did they want to) a 4 footer on the Wisconsin River just south of Sauk City. There were photos in the paper taken by canoists etc but no one did ever capture it.
There was also the 7-8 pirrahna caught out of lake columbia near Portage.
And I saw my first ever albino deer two weeks ago. A buck, a fawn and a doe. All feeding together, away from the other deer. The buck had white velvet. Kinda cool.
