For those of you on Strava, he's posting some updates like this one with their app.
Steve Weixel walked 0.0 mi and climbed 0 ft on Nurse's Station Loop
about 12 hours ago with the Strava iPhone App
and a comment about the same from his wife (I assume wife, I don't know them well at all):
"There were a few wheel touches (IV stand and walker) but everyone managed to stay upright."
Best wishes to him and all others involved or otherwise healing. Also, kudos to umd and his wife for their positive attitudes.
