That statement is very true. Whenever Mr. B goes for one of his 2 mile walks OG & EJ tag along with a plastic grocery bag. They pick up all the discarded soda and beer cans along the roadside. They bring them home and dump them into a large garbage can. When the can is full ... ... they bag up the aluminum cans. JP then drives them down to the salvage center.
They return with M$NEY!! Yep, this is how our little OG & EJ earn their spending money. We've taught our children to use the envelope system for their money. They put 10% into a tithe/offerings envelope and divide the remaining 90% between a savings envelope and a spend envelope. About every 6 weeks the savings envelope is deposited at the bank into their dowry/college savings funds.
