Wednesday's Smart Talk is being broadcast live from the Pennsylvania Farm Show.

In what has become a bit of a tradition, the live broadcast acts as a "State of Agriculture in Pennsylvania."

Pennsylvania Secretary of the Department of Agriculture Russell Redding joins us to discuss the challenges facing the state's farmers and Ag-related industries. It's the 10th edition of the Farm Show this year so we'll discuss the history and what the world's largest indoor agricultural exhibition means to the state.

Another tradition that Farm Show visitors look forward to every year is the milkshakes. For 60 years, milkshakes have come in just two flavors -- vanilla and chocolate. This year the strawberry and cream milkshake made its debut. We'll find out why that's significant.

Mushrooms are a highlight of the 2016 Farm Show. Pennsylvania is the nation's leading mushroom producing state and we'll hear from the Pennsylvania Mushroom Farmers.

Finally, a display getting attention at this year's show is sponsored by the Pennsylvania Landscape and Nursery Association. During the show, we'll address land environmental restoration.
