“I’m too old for this!” said Lori Knuteson, laughing while she dug a trench in the soil of the victory garden at the Northeast Georgia History Center. Knuteson and her fellow Master Gardeners are digging the necessary trench for a new irrigation system at the garden, which produces fruits and vegetables for two local nonprofit organizations. The trench has to be 4 inches wide, a foot deep and approximately 40 feet long.
