I can't remember where the thread was, but someone actually did a test on this. They wrapped it really well, and then when they thawed it they put a fan on it which kept it from having such a bad condensation problem. They said it was as fresh tasting and looking as the day they froze it! You can do a search in the forums and you may be able to find it. I wouldn't put any flowers or decorations like that on it, but you could do the basic stuff.
I actually saved that post about the freezing experiement=) Here is the link...
