Don’t know if he was in the park then but that sounds like it could be him.  Last summer my 12 year old nephew and I were headed north.  We had been driving constantly from Chicago and pulled in to a gas station in Superior.  While filling up my nephew said hay the guy behind us has a canoe on too. I finally turned around and there was KF.  With a real stern look on my face I pointed at him.  He looked up and saw me pointing and got this what is that guys problem look.  Then he recognized me and we chatted for a few minutes before we both were on our way.
