May Day Prague flowers...

Since it is May Day (or Socialist Workers Day) and a holiday throughout Europe, here are a couple of pictures of some fields around Horomerice. The fields contain some kind of crop with amazing yellow flowers. I did a bit of research (ah, Google, is there anything you don't know?) and it seems that the plants are canola or rapeseed (are those two the same thing?). Anyway, it is a sight, indeed, to see acres and acres of these bright yellow flowers.
