We are traveling to Thunder Bay via Minneapolis airport and are looking for an inexpensive way to get there (and back). Don't really want to do a rental car because we won't need a car while in Thunder Bay for 7-8 days. Are there trains, buslines or perhaps ferries across Lake Superior that could be used as alternatives to driving? Anyone know of any good deals or perhaps reasonable one-way car rentals to make the 6-7 hour (is that about right?) drive? The locals ought to know.. -Gerry
