I both love and hate the postseason for this reason, there are always always always way more ducks around than you'd ever see during the season and they'll be in all of the spots you were hunting throughout the year in large numbers. I went out to shoot a few crows recently and my first shot of the day was purposefully long enough after legal time to be sure that I'd see at least how many ducks and geese would get up from the surrounding areas and I was in awe. To see several hundred come from a hole that you never see more than a dozen in during the season is amazing, but also a little heartbreaking.
lots of blacks and mallards and ever a few divers well inland, and of course a pile of geese are around. what I would give to hunt through the end of feb instead of January!
