I did make a second visit to the chiropractor yesterday, and it seemed to help somewhat.  But when I woke up this morning I could barely move.  Happily things loosened up some as the morning wore on, so I did go with Tom to see Alex.  We also met his boss Nick, who raved about what a great employee Alex is - and gave us some credit for that. While I did (finally) get to see a bus this time, it turned out to again be a replacement for their usual one.  We stayed less than an hour - Alex had other things to do - but he'll be home in a week or so for some R & R.
