Stuff before surgery

So, it looks as though dad will go to Ann Arbor on the 18th for his shot. And then results will be read at 1 hour, 2 hours and 24 hours and then he will come back home. He also has to be there on the 22nd for more tests and then back the 23rd for surgery. Lots of busyness, but he mentioned that at least he gets paid a little bit for doing the clinical trial. One cool way to look at it.
