Jimmy thats why the Federal government makes thermals readily available to the unimportant little nobodies such as ourselves!LOL Jim you hunt in Canada you should have the correct attire for the cold! especially on the lake!!! :):):):)
I've hunted it several times. The site does hold silver and the possibility of other pre-American finds. Father Marquette exited Lake Michigan at Marquette Park at the mouth of the Calumet river. The river mouth is gone but you can see where it was.
I would like to hit some of the Parks in Chicago. Solo is sometimes uncomfortable but 6 or 7 guys in Pullman park can sure have a good time. I would love to get something going in the fall. Have dine a lot of research and all we need to do now is take the ride.
