I guess I'm spoiled, as I live about 300 ft away from 4 recycling bins. Since this is a small municipality, I just go up once a week and grab a trunk load of newspapers/cardboard out of them.
I am not sure if it's fine if I do that or not, but at worst I figure I can always use the logic that I'm saving the municipality a lot of money each year. Usually every 1.5 weeks a large truck comes and takes the stuff in the containers to a recycling plant 1.5 hours away - I figure that's at least a $300 charge.

Not exactly a freebie, but I find it to be a miracle considering how remote we are. Last week a guy from the classifieds delivered(35km away) three 1000L totes for $100 total, all of which previously had a canola oil-ish product in them for use in commercial drills. He had lots of scrap metal in the back of his truck at the time, so I inquired about any good finds - hopefully that will lead to some freebies in the future.
