I'd recommend reading 'Bows and Arrows of the Native Americans' by Jim Hamm and subscribing to 'Primitive Archer' magazine.

Oak is a fair bow wood. Not so hot for arrow wood though. Dogwood, wild rose, ash (also decent bow wood), tamarisk (salt cedar) and yaupon are some of the better arrow woods that grow in my neck of the woods. I don't know what you've got up yonder.
