i was just over at bwca to check for follow up info.the guy was overnite at the local hospital and was still weak but ok when he left.the RN on the rescue plane put ice packs under his armpits and groin to cool him down.another bit of luck was not only the fellows from bwca.com who were there to help but that this lake,Fourtown,is large enough to land a float plane.in a smaller lake or halfway across a portage they may of had to call in a chopper and all the time and hassle that would involved.
