Who can tell?
Maybe there are select stashes of Thai based seeds near Portland. Could be that Eugene is the world's center for various strains of Trainwreck.
Who knows? I don't.
I would bet that in Grants Pass there are seeds of the highest order. La Grande, Brookings and Bend have stellar reputations for reliable cannabis genetics from what I've heard which is very little really.
Good luck in your quest.
