Wolf, Corbett troll for votes at farm expo
For a few days in August thousands of farmers from across the state turn off their tractors and head over to the Penn State ag research center near State College to learn about the latest agriculture innovations - the newest "liquid containment systems" (otherwise known as manure pits), the latest in cow cooling technology and GPS systems for planting. On at least one of those days farmers are trailed by political candidates who flock to Ag Progress Days in search of votes.On Wednesday Gov. Corbett and his Democratic challenger Tom Wolf both had their chance to make farm friendly pitches to rural voters at the annual government and industry day luncheon.
