Dave Fuller is our guest on this week's episode of the Great Loop Radio podcast. This is the time of year that many Loopers are cruising Georgian Bay and the North Channel.  As you wrap up the North Channel, Dave recommends taking a side trip to Sault Ste. Marie, Ontario for a train tour to Agawa Canyon, and then heading to Lake Superior to visit Whitefish point.  Listen to learn why this is a unique and fascinating side trip to your Great Loop adventure!
