My obsession with MI septarians paid off with this 100 LBSer

I found a new spot recently for finding Michigan septarians or Lightning Stones as a lot of locals call them. I used to be lucky to find one where I could make a 2 -3 inch sphere out of them. But recently, I've been getting my feet wet a bit and dragging some lunkers out of Lake Michigan. This is a pic of a 100+ pounder my friend helped me get out. There is a 30 pounder in the background. If I can cut or core the thing I may be able to make a five to seven 5-6" spheres out of it. This is by far the biggest one I've found with such good patterns most likely inside. It sunk the raft I had brought to bring it back so we had to improvise. I found an old dock section that had washed up on shore and used that as a raft to pull it about a mile through the water then up a huge incline to the car. I couldn't move the next day hardly, I was so sore. The only bad thing was I found a probly equal size amazing pudding stone in the water on the way back, and may have to go back for it, so I can get a good nights rest!
