If you see something out of place. Shoot it and upload it. This will become a huge collection. Long term, I'm hoping one day to have enough photos to make a coffee table / toilet book. If I use your photo within the book, I'd like to offer $30. I plucked that figure out of the air because a) I might never have enough photos for the book and b) I have no idea if people will buy the book. This is really early days but I wanted to state my intentions from the start.
