So why not organize a "Can Film Festival." Approach a local movie theatre or theatre chain and ask if, say, over a particular weekend, they'd be willing to give a discount to everyone who brings in a can of food. Volunteer to get a group together to bring all the cans to a previously identified shelter or food bank that has given its blessing to the project.
Not into film? Well, the Super Bowl approaches on February 1. If you're hosting a party, consider making it a truly "Souper Event" by asking guests to bring one or more cans of Progresso, Campbells, or any other brand. Then take the goods to a local shelter or bank. Imagine what would happen if a goodly portion of Super Bowl party attendees did this.
