I was going with Ash myself. I haven't cut one this mature/big yet. Mostly cut tall pecker poles in the woods. The depth of the bark had me second guessing. That and I couldn't really make out any EAB holes in it. My old man swore it was Box Elder. I've done a couple google searches this morning on ash and box elder. It definitely fits the Ash descriptions and pics I found. However, Box Elder leaves look pretty close and even the bark is somewhat similar. Plus, my mom has a ton of box elder bugs that hang out on the side of her house.
Hedgerow, I just notice the dead ones and there is a ton of them! I've cut quite a lot of them since I started cutting in fall '08. Probably 25-30 full cords worth. Too bad, they're nice trees really.
Thanks guys! Looks like some good firewood is coming my way! Just gotta figure out where to lay it.
