An entire field of Buttercups! I don't know how the cattle feel about this in their pasture, but every year the field turns bright yellow, and it's not Dandelions!
Can you see the fence? Just the very tops of the posts showing, down in the ditch.
This is a pair of fields we drive by frequently; this time it was driving home from picking up our dog at our daughter's place after we got back farom up north.
And these two close-ups I got right here in the garden (where they're 'weeds'). All shot with my new pocket Lumix, and I'm not entirely satisfied with the focus on close ones, but it's pretty good. I let the background be pretty dark in these two, to try and emphasize the form within the flower.
