I found some on  a portage on the Man Chain years ago.  

We call them honeycombs here.  They bring a high $ selling them.  Three or four years ago I was getting up close to $60 a gallon for them.
For us we tend to find them on a hill sides facing southeast near big elm trees.  We take them string a thread thru them, hang upside down in a dark closet and have them to eat all year long, providing we can keep from eating them that long.
