Peterborough is another great stop with a lot of nearby facilities.  We rode our bikes to the Peterborough Museum which covers the history of the area.  We then rode on to the Peterborough Lift Lock (Lock 21 on the Trent Severn Waterway).
The lock was built between 1896 and 1904.  It raises and lowers boats in 2 water-filled chambers, each of which is 140 feet long and holds 228,000 gallons of water weighing 1,700 tons.  The two 7-1/2-foot diameter chamber rams – each with a lifting reach of 65 feet – are connected in a closed water hydraulic system.  Any movement in one chamber must force an equal and opposite movement of the other chamber. 
To transfer boats, the upper chamber is overbalanced by taking on an extra foot of water.  When the valve connecting the hydraulic rams is opened, the heavier upper chamber travels downward, forcing the opposite chamber an equal distance upward.   It is amazing and fascinating to watch.  Even today it is considered an engineering wonder.      
After touring the lock and the lock Welcome Center, we rode back to the boats and enjoyed a melt-in-your-mouth salmon dinner compliments of Bade Boomer, grilled by Chef Carlton.  Yum!

  1. As an artist myself, I enjoy reading Philip Koch's sensitive writing about Edward Hopper and Andrew Wyeth, who along with Whistler and Rothko, are my favorite American painters.
    I don't live in the United States but have traveled and passed a short time there. But even with the little time spent in your beautiful country, especially in small-town America, I can relate to some of the poetical feel that Hopper and Wyeth had captured in their art, which is for me part of the attraction of their paintings.
    Browsing at the other day, as I do now and then, I find a good selection of Edward Hopper's work, ,in the big archive of Western Art, that customers can order online for canvas prints and even hand-painted, oil-painting reproductions can be made and sent to them.
    Hopper's surrealistic and depersonalized world is there again. Timeless, yes, as it is still there now in the roadside cafes and diners that I ate at all over America.
