Looks like Nancy is delayed. I hope it is due to something unexpectedly good and not bad (thinking of you TM).
Anyway, here is something to fill the void. Nancy, feel free to post your planned question which is probably MUCH more interesting than this one!
Since we covered the current most widely grown plant yesterday, would you like to try to come up with what was the world's largest agricultural crop before 1883? I haven't come up with any good clues yet, but will think and return with help for you.
