What effect(or how large?) does a hard winter have on antler development the next year?

I have been thinking about this as I watch 07-08 winter become one of the hardest winters in the past 10 years for this area. Right now it is around 0 with 1-2 feet of snow over everything. It has been entirely snow covered (not counting a short melt about three weeks ago) for the last 2 months too.

I am asking all those who have many more years in a treestand than I in the 'north'. We all know that if you starve a buck, it would theoretically have a smaller rack than if the buck had a full belly all winter long. Does this carry through to what people see? If it does, how great is the effect? Can you visibly see smaller racks after a really hard winter?

I know this varies geographically also. The northwoods have much harder (measured in this case by ability of wildlife to find food) winters than my area of farmland. Do you think the effect would be noticible in northern WI, but not IA or southern WI?

Whats your opinion, taking into account physical location and local resources for your area?
