This is exactly the thread I needed to tell about the best find ever, though I didn't even think about picking it up, and it really wasn't the best find. I was in Saskatchewan and I found a ***** on the side of the road. Pretty bizzare.
I think the most interesting thing about finding things on the side of the road is the possible story behind then getting there, or thinking of the person that might have owned the item. At some point they must have cared enough to buy the item, but for some things (like the many cellphones I've seen) there must have been some reason for them to be thrown out the window.
