I have done it a couple times now. First time, my two buddies and I scored one snow each. We didn't have any decoys so we used plastic trash bags - they worked.
Second time, I got a blind with three other guys. One person was a total idiot (luck of the draw and getting assigned with one). We were finished by 9:00, this idiot was too much. The idiotic had some rags with him and we set up those.
The blind will be a concrete ditch with a box over it. Bring camo cover for the box. Bring decoys if you can get some. And, practice your snow goose calling.
I didn't put in this year because my hunting buddy was starting out a new job.
