A side note: A big cave complex has been found in my area here in Illinois originally named Burrows cave, but Burrows says his cave isn't the same but is nearby. Ancient Indian (not American Indian, India Indian!) artifacts from 5000 BC, I believe, have been found in it. The newest edition of "Ancient American" magazine has some of the details. I grew up in the Embarras River valley which is the valley where the cave is. I don't know if it's the same part of the valley, the cave's exact location is still being kept secret for fear of looting.
Yup. I saw that in my copy but haven't read it yet.
