I doubt that it would cost too much to buy that first store at 501 N. Michigan Street (the Old Route 66) in Joliet, Illinois, and would like to see Dairy Queen buy it and turn it into a museum for the company.
I'm sure Joliet would help out in some ways, what with their pride in their history and Route 66. Perhaps, Dairy Queen could also build one of their retro places across the street and have a similar setup as McDonald's does at their first Ray Kroc store in Des Plaines, Illinois.
That would sure be a big stop for all those traveling Route 66 through Illinois.
Come On, dairy Queen. --RoadDog
