Kansas is not in the north either, but it's been working here for twenty years or better regardless of vi's claims that it won't. 

I've never seen a situation yet where you had to keep grain longer then a year without the opportunity to refreeze it.  Funny how winter always seems to come back.    

Wheat is the problem child.....it's a real challenge to get it from harvest to winter.  Once you make it to winter, it isn't much different then any other grain.
