Yep, Bigleaf. You will not find Locust in the woods, it is not native here. There is some around the towns, but good luck with that. You need to get a good field guide for western Wa. there are tons of usable woods...Yew, Cascara, Vinemaple, Ocean spray, Ash, Hawthorn, Bigleaf maple, Dogwood, (pacific flowering) Plum. ect.....
