What's Up, Buttercups?

I've been going to work the last couple of days for an open house, but I thought I'd share a few pictures:

A few pastures along the road to work are absolutely loaded with Buttercups (Ranunculus sp).  The plant is toxic to wildlife and farm animals, who wisely seem to avoid it unless there's nothing left available, which makes it a common weed in the pastures.
