I was in Guelph earlier today and as I drove by the downtown core, the remains of an old stone facade caught my eye. It was down an embankment, near the river. Parking nearby I stumbled upon (literally) a nice little walking trail that followed the river and a rail line. An unused rail bridge created some interesting shadows.
A little further along, the sun found a hole through the riverside tree cover to spotlight a small window into the river against a reflection of the old mill on the opposite bank.
