They might rot, even if treated with a fungicide; that's a long time to be in the ground. They also might start to germinate if you have a January (or Feb.) thaw and then it gets really cold again. I always planted my peas in IN around mid-late March -- I take it you aren't back by then -- know anyone who would trade an extra row of peas for some fresh citrus fruit? You might be able to work out a trade!

I'm not thinking the seed would survive. But
with a heavy snow cover..............

I'd certainly give it a try. Even if it only worked once every couple of years, it would still be cool.
I still think its a long shot tho.
