Holy Moly, what an incredible post. Sure hope you heal up fast, and there aren't any lingering problems with your unreplaceable self.
The photos are amazing. I showed them to my little smartie, reminding her how dangerous stupid, cell-yaking, oblivious drivers are, and she promised to be extra careful, (and that she thought the new heated seats will probably help your back feel better - very, very soon.)
You and John H should talk - you two electronics brainiacs might save the world.
Again, so happy you're (hopefully) a-0k, and I'm confident your new smartie will again bring the same smart joy in which we all love to wallow.
