Wintering Dahlias

[BlueBee]

I got my Dahlia tubers dug up this week.  Below is a photo of some.

For you Dahlia growers out there, how do you winter your tubers?  

There's about as many theories on wintering Dahlias as there are on bees, LOL.  If they get too wet, they rot away.  If they get too dry, they shrivel up and die.  If they get below 32F, they freeze and die.  If they get too hot, they sprout too soon.  So what do you do :?
