Directions to Observatory

Directions for the location of John Rudy Park Observatory. Take Rt. 30 to Rt 24 exit, and go north over the hill. When you get to the bottom of the hill, turn right at the traffic light. Go over the creek, and turn left at the "S" turn----be careful, and watch for southbound speeders. Go about 1/2 mile, turn right into the park at the split rail fence. The observatory is in the field off to the left of the gravel parking lot. At night look for the red light  at observatory.
