"Now that the economy has taken a down turn and people are concerned on where their food supply comes from, they are very interested in preserving their own food," Extension Agent Pat Whitaker told Nashville's News 2.
He continued, "Our classes are filled with master gardeners, basic gardeners, and people learning vegetable gardening. The farmers markets are bursting at the seams with people wanting good fresh, locally grown produce if at all possible."
There were 22 students in Tuesday morning's class, including Bill Eakes.
He told Nashville's News 2 he wanted to learn how to preserve his home grown vegetables.
"Instead of giving them all away and trying to get rid of them and having extras and composting, I figure I can [put them into cans] and eat them during the winter and have fresh vegetables during the winter," he said.
Patty Carpenter took the canning class to conquer her fears.
She said, "I'm here to overcome that fear because I want to can and preserve my own foods. I am very cautious about what I eat and what I feed my family."
"It is a thrill to watch people learn how to do it," Whitaker said, adding that once you learn the basics and know the steps of canning, anyone can be successful at it.
According to Whitaker, modern pressure cookers are very safe and can be found at most stores but said yard sales are a good place to look to save money.
