Well, I don't think you're gonna be able to plant and harvest beans with what's left of this year, but folks aroung here just snap the ends and string the beans, leave them whole, and string them on pieces of cotton string about 2-3 feet long. Then leave them in the sun, turning them occasionally, until they dry out. They'll keep like that for a long time as long as they don't get wet or spend a lot of time in a really humid place.
We always called them "leather britches", or "string beans". They're really good eatin' cooked up shuck and all with plenty of bacon grease. :grin:
I don't have any idea if it's PC or not, but that's the way the old folks here have been doing it for as long as I remember.
