Sorry for the lousy pic, it was taken from the bike when we were in a relative hurry on our 600k:
As we crossed the Beauce (crop-growing region south of Paris) there was field upon field of the stuff. It looks like a variety of poppy but the only reason for growing poppies I could think of would attract a little attention from the
flics. Anyway, they're a bit too white for that.
Any ideas?
