I've been several times, most recently this Monday and Tuesday. Bird numbers in the Northeast in general are very good, historically speaking. IME, it's comparable to last year which was a good year. I shot a limit Tuesday, all on WIA ground, which is always a cause for celebration in CO. I didn't have a bird of either sex flush in range on Monday, and only saw a few birds, which is typical.
Birds were noticeably more bunched up this week compared to a few weeks ago. Not many singles and doubles, but a few groups of 12-20. That's only going to increase as the winter weather comes on. They've been spooky as all get out throughout the season (and even were flushing wild when I was just driving around scouting a couple weeks before the opener).
Corn is 98% out now. That was an issue earlier in the season. There has been quite a bit of stalk baling too in certain areas, which can be good or bad depending on your perspective (leaves less in the field for cover and mooshes the food into the dirt, but also concentrates birds in adjacent cover).
If you can go weekdays - you won't see anyone else. I hunted dawn to dusk both monday and tuesday and literally saw 0 other hunters.
