I have family in KY and WI and have found sources of white pine in both $.60/bdft .If I'm patient i can get boards 14" + wide .Because of the longer growing season the boards from KY have about 4-6 growth rings per inch. The boards from WI about twice that.
Is one board going to be more stable than the other board? My uncle who has made a living as a cabinet maker and carpenter said it doesn't matter with white pine. I'll be making craft stuff crates, boxes,and chests

Some boards from KY. Definitely not old growth that's for sure
