Thanks everybody, I really appreciate all the good advice.
I think I may cut both ash, and elm. I need lots of hands on experience with this, so it makes sense to have a bunch on hand.
John, thanks for the link to your ash bow, It's a big help. Also the info regarding bringing the wood down to near bow dimensions, and then drying it quickly.
Glen, that's a generous offer, thank you. I don't see myself getting down that way any time soon, but if I do, I'll take you up on it. Thanks again.
I found a copy of The Traditional Bowyers Bible, vol 1, at my local library. It's a great book, and I'm going to have to get my own copy.
I'll use the search function first next time, but I'm sure I'll have more questions for you guys, if you don't mind. Thanks a lot.
Bob
