Maid(s) of the Mist @ Niagara Falls

Niagara Falls is really three falls:  American, Bridal Veil and the Canadian Horseshoe Falls.  One fifth of all the fresh water in the world comes from four of the Great Lakes and the outflow travels to the Niagara River and eventually cascades over the falls.  It is a magnificent sight.  My travel "Maids" and I were filled with awe.  Three of us walked across the Rainbow Bridge (passports in hand) into the province of Ontario, Canada.  The view is even more spectacular from the Canadian side. The water thunders down and lands in Lake Ontario.  From there it flows to the St. Lawrence Seaway and then on to the Atlantic Ocean.  When the boat, Maid of the Mist, took us below the Horseshoe Falls we were saturated in seconds and the sun shone through the water and created a rainbow that mimicked its namesake bridge.  The depth of the water is 170 feet which gives it a greenish cast. Above us the seagulls are squawking and diving even as the boat struggles to turn in a half circle and return us to the safety of the dock.
