Ahoy mateys! Just got the news that Dad's foot infection has cleared up enough that the doc told him it doesn't appear amputation will be needed. That means that Dad is finally able to fight off infection without having to go to the hospital and get pumped full of IV stuff--he fought it off at home all by his lil ole self. Of course at his age nothing is guaranteed, but of course, it being Dad and all, he's completely optimistic about all of this.
Thanks to all for your good thoughts and prayers.
