When US 23 divides, take a right on to SR 42. DON'T turn in at the Church Camp. DON'T turn in at the Indian Springs Park entrance. Go on past the entrance until you come to the caution light. Turn right at the caution light and just go straight for a mile or two.
Registration is at the first building inside the gate.
You'll need to pick up your parking permit here. Then just straigh ahead to the observing field. Telescopes are left on the field. You'll want a plastic tarp and bungee cords to cover your scope after you're through observing to protect it from dew and dust. Since you are own your own for meals, I always take a supply of soft drinks, snacks, and fruit.
