Yellow Fields

As I was driving with my parents last week, we kept seeing these fields that were completely yellow. My mom said she could even see these fields when her plane was landing. We had a few guesses as to what it was, but didn't really know (knowing how many dandelions I have in my own yard, that was the first thing that came to my mind). Well, we Googled it when we got home and found out that they were fields of rapeseed flowers. According to Wikipedia, rapeseed is grown for the production of animal feed, vegetable oil (including canola oil), and biodiesel.I couldn't help but look out as I was driving, and be reminded of the yellow brick road from the Wizard of Oz (I guess the fact that I'm reading "Wicked" right now may have something to do with that.)
