Since you've got so many beans, you might want to try making
"leather britches": http://www.motherearthnews.com/real-...#axzz2ZDsv6vNg

My mom's family would hang them in the attic (100-120oF or so) to dry, or if
it was a dry summer, just place them on screens on the roof to dry.

If you like the version of green beans where you cook them with bacon
or a ham shank till they're Really Dead, you'll probably like these.
It is a different flavor and texture from fresh or frozen beans cooked
until they're just done.
