1988 Fuji Mt. Fuji Mountain Bike, Blackburn rear rack, milk crate on each side, used nylon wire ties to attach the crates, a plastic soda case (24 can) crate on top. I used it to carry 8 to 10 twenty pound bags of ice at a time from the convenience store to the night club, about one mile each way. Sometimes had to make more than one trip a night, it was a bit wobbly, but it worked. (Yes, I did complain when the ice maker was fixed.)
