We have gone down a couple of steps just inside the door. There are a few exhibits down here and we could enter a couple of rooms used for camps, special events, etc.
One of the exhibits is a picture with a view of Columbus from 60,000 feet in the air. A rock, taken from near I-270 and 161 in 1969, also sits around here. It's believed to be about 360 million years old!
Go back up to look at rest of the Solar Front.
