A nickel bottle deposit was a lot more incentive to bother with collecting bottles and cans when you could get a coke for a quarter, than now when you need to trade in grocery bag full.
I remember in the 90s, we would always trade in our bottles before we went to the county fair, and that was enough for admission and rides and some fair food. I don't think the barrels and barrels of cans would get us in the gate anymore.
