Screw them boards man..your in the eastern woodlands,which is land of many trees....go find n cut some saplings and small trees and reduce em down to near bow dimension and quick dry them..you can have something semi dry enough to bend on in a week if ya want. Go look for hickory,elm,oaks,all those grow plenty in your area and will be easy to find clean n straight. Also you have hophornbeam,sugar maple,white ash,etc...a plethora of free wood surrounds you.
