Toronto. My friend Goldie was wandering around the Fisher Rare Book Library on the U of T campus when he discovered photos of the Dawson Creek area around 1898-1901 (during the gold rush). The photos were taken by Joseph Burr Tyrrell. He was a famous Canadian as noted by this text in the Canadian Encyclopedia.
There is even a museum named after him just outside Drumheller. My youngest daughter and I visited the Royal Tyrrell Museum a bit over 15 years ago. It is a small museum with some amazing dinosaur bones and other artifacts.
I had a Leica M4 with me at the time while my daughter had a Canon AE-1. I used ASA800 Fuji Colour Film and had alkaline cells in my Gossen-Pro since mercury cells were banned by then. The built in meter of the AE-1 was used to calibrate the Gossen-Pro. Alkaline cells proved to be relatively stable when fresh. If Gossen had spent a few pennies more, a bridge circuit could have been used making voltage variations irrelevant. Their crude meter, battery, resistor circuit relied on the stability of the mercury cells which had a constant voltage until almost dead.
