June 10th,  Chicago, Illinois.   GM   The plan was simple.  Mr. Landis organized some of the kids from the last trip, though this one was less involved in showing the woods and general survival tips (though the two students who demonstrated skill in the outdoors was a small bit of surprise).  So this time it was a shift to an urban environment.  Specifically his old stomping grounds given that he went to college at Northwestern.  And since it was the end of the term, it made things even easier.
