White Pine (Pinus strobus) seedling.
Queen Anne's Lace (Daucus carota) - aka: Bird's Nest
I didn't ID this at the time. I think it's Blackberry, though (Rubus spp.)
Of course by now it's all melted away, but it sure made for a pretty morning drive.
Update: according to Dear ol' Dad, the piece of farm equipment pictured above is "an old critter-powered road grader used to smooth dirt and gravel roads when they became rutted and full of holes. Too bad there isn't something similar for asphalt highway potholes!" Thanks, Dad!
