My goodness, that's half a million cucumbers! How big is your garden? Who counted all those cukes?
Let's see...you could can dill pickles whole and sliced into chips, bread and butter pickles, and cucumber relish. Then there's cucumbers and onions marinated in white vinigar, salt and sugar as a side dish. And there about as many recipes for cucumber salads as you have cucumbers.
I thing you have enough cukes to eat your fill and give away a bunch, too.
