That looks like a chunky Northern.
Most of my experience with them was in Cherokee NF, and those were all much smaller guys. Regardless of species, it always sends a shock through me when any snake pops out of nowhere around me.
I think your list pretty closely matches mine except with the following modifications:
1a. a bear carrying a copperhead and rattlesnake
1b. a Rosie O'Donnell lead PETA march along Little River Trail.
One exception would be that if both 1a & 1b above were to occur simultaneously. That would make for an interesting show.
