Hwy. 18 going into Jefferson from Cambridge is under road construction.  You cannot get into the show grounds from Hwy. 18.  The best way for you would be to come the freeway to Hwy. 26.  Take a right on Hwy 26 South going towards Jefferson.  Right before you get into Jefferson you will see a trailer park on the LEFT side.  The first stop light is Puerner Street.  Turn right on Puerner (which is at the stop light) and Puerner runs right into the show grounds.
