There were some great guesses on #1 and Mac from England got it right off. Maybe he has a run in with a Teasel. This is a top view of the dangerous plant. Here is a side view if the top view confused you.
The snow on my windshield above the windshield wipers as I drove to the hospital for exercise. I thought that build-up may be confusing. Darla from Florida got this one first, that was a surprise to me.
The blooming of the Tamarack Tree. This is the largest stand of them in USA in the Kent Bog. I showed the tree in my Triangle Lake post a few weeks back. Look here to see them in bloom. My friend Tom from the ODNR had worked at the bog and he knew what it was. You really had to pay attention to get this one.
