Well, I stopped mowing for a short rest, so cooling off here with a glass of lemonade and looking at TBN.
Mike, as for keeping spuds.... Wait until vines die completely before digging, but not so long as to let damp soil encourage rot. If you dig them and the skins slip off easily, you have dug them too early. You should be able to handle them without slipping any skin off.
When we dig, we lay out on the dirt for awhile to encourage dirt to dry ...hopefully you will be digging sometime in Sep or around labor day...when there is usually a dry spell and the dirt comes off easily. Doesn't always work that way...but usually does for us.
As for keeping... put in absolutely dark place that remains cool. At our old farm house I grew up in, we had a building (shed) that we called the well house. Half of the shed covered a hand dug well, the other half was a cellar. The cellar had dirt floors and double walls. Between the 2 walls there was sawdust, and also there was sawdust above the ceiling. (this was insulation they used to use). We had bins in there where we kept our potatoes and shelves for canned goods out of the garden. It was a great place to keep potatoes.
Here at my current home, I haven't raised huge crops, and usually keep mine in several 5 gallon buckets. I keep in my basement, back in a dark corner. Even a small amount of light from a light bulb is enough to turn them green over time.
I have read where some people dig a pit in the ground and lay wood and straw bales over the top to insulate from the winter cold, and use this to store root crops. Around here, you used to see a lot of cellars built into hill sides , maybe layed up with block, and with dirt covering the roof.
I think it would be easy to build a small shed with dirt floor and insulate heavily so things would not freeze. Wouldn't have to be too big to store what you would eat in a winter.
You want to keep rotating your stash...and throwing out any bad ones. Nothing worse than sticking your fingers into a rotten potato. I used to delight in seeing my sisters dig their hands into a rotten potato when we were digging. Usually there would be varied exclaimations, followed by rubbing the offending goo off on some dry dirt. To a boy, that was pure delight.
