just wondering what you guys think about the wood in the pics. On the left in each frame is lovely Ash but on the right is something I'm not familiar with. It is tough as nails to split, whether its frozen or warm. I cut a shortie and split it for you but it took about 5 whacks and its real stringy. If I have any larger pieces I'll have to cookie them to fit into the stove. Any thoughts on what it could be???
