And yep.........they can become pretty addictive. I started with just a few tubers about 8-9 years ago, and am up to close to 150 this year.
Dry and cold is the key to storage, and I'll bet in CO you should do fine. find a corner in your basement or the bottom of a closet that is on the outside of your home. You are likely to lose a few, as some tubers are more difficult to store than others, but many store very easily.
