Here is another excellent reason for buying/eating locally grown grub.
"A town of 10,000 can spend roughly $15 million yearly on food products. If only 10 percent of the $15 million is purchased from local growers, $1.5 million would be kept in our local economy. This money could be re-spent to benefit other businesses, the school system, and city and county budgets. "
