Take advantage of this once-a-year opportunity to learn about local agriculture during the Open Gate Farm Tour sponsored by Penn State Extension in Lehigh County. Agriculture in Lehigh County has many faces. This annual event has been conducted in Lehigh County for over 45 years. There is no charge to go to any of these sites. Visit as many or as few as you like. Bring your family to any of these locations on Sunday, October 18th, between the hours of 1:00 and 5:00 p.m. It’s rain or shine. Dress casually and enjoy the day!
