i will be in chicago next week and want to go hiking...i have all the gear for very cold weather and am willing to drive 6 maybe even 7 hours if it's epic...i'm contemplating going all the way to the U.P. but would happily settle for the ice age trail if there is something sweet to see...i'm looking to do 30 to 50 miles preferably a loop and will have my dog...i'm doing some research now but am hoping for a couple stellar suggestions...thanks!
