For any photographers who have visited or are interested in visiting Sax Zim Bog in MN for boreal species, here's some news. Mike Hendrickson sent an email to the MOU list. He's the organizer of the winter bird festival there (which was this past weekend.)
The news is that the DNR has cracked down on the feeders and removed the deer carcasses that various people had placed around the Bog. Certain locals claim that they are attracting wolves and other undesirable wildlife. My personal opinion is that some of the locals really don't like the influx of birders and photograhers, rather than wolves. It seems to me that if there were really so many wolves all over the place, people would be seeing them instead of birds.
These feeders are the stations that were located on Admiral Rd, Arkola Rd, and McDavitt Rd. They were basically just ad-hoc feeders stations that had been set up along public roads. Various local people would keep them stocked with seed and frozen deer carcasses. Probably the greatest loss from these feeders is being able to easily find boreal chickadees. The McDavitt Rd feeder in particular was really well suited for photography. People came from all over the country to visit this feeder and see boreal chickadees, gray jays, etc. It's a real shame that it has been taken down. I guess these feeders were victims to their own success. 
Note that there are still private landowners who make their feeders available to the public (mostly good for finches and grosbeaks.) Also there are still plenty of owls and woodpeckers around. So the Bog is still worth a visit, even if you're much less likely to see and get close to a boreal chickadee.
Here are a few shots I've taken at the McDavitt Rd feeder:
