From the Niagara Gazette:
The cannon will fire again for LaSalle, Hennepin & Company at the 12th annual Niagara Falls Boom Days set for 7 p.m. on Saturday.
This date will mark the 125th anniversary of the formation of the City of Niagara Falls, completed when the Town of LaSalle incorporated itself to the city in 1927, but Boom Days has an older tradition in which it honors Cavalier LaSalle and Father Hennepin who opened the fur trade up for the France and crossed the Great Lakes to Wisconsin in 1679 from Griffin Park Boat Locks.
In full costume, Kenneth Sherman will play the explorer LaSalle while Walter Kendzia plays Father Hennepin, and both will paddle from Griffon Park Boat Locks to the LaSalle Yacht Club with any would-be companions.
