I live near, and teach at Fordyce. My wife has an uncle that lives at Mt Ida, and he has always been picking up rocks and such..... for as long as I have known him. I have lined the flower beds in front of my house with petrified wood and quartz aggregates, etc from his old houseplace near my home. Give me an email at reliccsa54@yahoo.com and I'll give you a bit more info. on him. I ask for the email, because I don't normally visit this forum..... just clicked on it for some reason this morning. And, it may be a long time before I check back in here.
