A cheap plastic/poly snow sled from WalMart works well too. I can't tell you how many deer I have hauled out of the woods with one. They go over logs, through mud and water and slide super easy over just about any type of ground cover. I like that they are small, light weight and do a really good job of keeping the deer up off the ground...preventing dirt, etc. from getting inside after field dressing.
I have never used one for hauling corn or stands, but don't see why it would not work for that.
