Underwater SCUBA park
Partner with the MacLaren or the Base Borden to create an underwater SCUBA park.
Barrie is a popular destination for Scuba diving instruction, but there is not a lot in Kempenfelt Bay to keep certified divers here.
I'm sure you would have an army of volunteers to scrub the artifacts to start the season.
