I am a member of a Facebook group called "Abandoned Alberta". The only real criteria is that the subject matter is abandoned. It is interesting what people find and post. I posted a few photos there. I mainly check the page to see what people find and to get some ideas.
I have found myself taking a second look at some places. I have passed this barn numerous times sitting just off a secondary highway when I go to visit relatives so I finally stopped to take a few photos.
