If you're going to collect old newspapers, you may just as well take cardboard too. Most people have old boxes around that are just taking up space, ad some will even pay you to get rid of them. You start clearing a space in your garage for storage. One side of a two-car garage, or just an 8 by 12 foot space would be sufficient. If you have a garden shed that is dry, that would work well also.
Some collectors even rent space in a neighborhood mini-warehouse.
Junk, old newspapers and cardboard boxes hauled away. Then visit your neighbors. Tell them you are collecting and hauling away all the old newspapers and boxes in the neighborhood each week. You drive the car with the trailer. Your helpers, one on each side of the street, knock on each door and ask the residents if they have any old newspapers or cardboard boxes you can haul away for them.
