We saw very good numbers between Minot and Devils Lake this past weekend as well. Not 250,000, but 20-30 flocks of over 100. Didn't get many to decoy though - too sunny and calm. We'll be headed back to the same area this weekend, there were very huntable numbers in the 3-4 flocks feeding in fields we saw on the way home too.
They're here, in at least a few places.
