What charities and shelters and soup kitchens need more than Chef Boyardee is.... MONEY. You can feed many more people if you buy $100 worth of stew meat and carrots and celery and taters and spices, than if you buy $100 of canned glop. Write a check, then volunteer to chop veggies and man the ladle.
The money should be coming from the federal, and state govts...instead of sending space ships to Mars.
Nothing wrong with canned soup, I eat it.
I don't volunteer for anything, because I believe everyone should be paid for their labour.
Also that volunteers get taken advantage of, are not always appreciated, and can suffer greatly if things go wrong...get sued, shunned, killed, burnt, etc.
