Taken a number of years ago at a recycling depot tank farm in the Portlands at the foot of Toronto close to Lake Ontario.
The Portlands is an interesting area that my photobuds and I prowl from time to time looking for eclectic subject matter.
On one bright, sunny f16 day I noticed the interesting shadows cast by the spiral staircase on the side of a large storage tank, and liking the composition, took this photo.
