Thirteen years ago I enrolled in the Cooperative Extension's Master Gardener training program in horticulture. I had felt comfortable gardening before taking the course, but I soon learned the science behind it. Community service is inherent in being a certified volunteer. Since being trained I have logged hundreds of hours gardening at the ' Dousman' Stagecoach Inn (1843); it is Brookfield's only building on the National Registry of Historic Places.
