Thanks for asking about Mom. She's doing quite well -- well enough, in fact, to take care of me these past few weeks as I've recuperated from surgery.

Here is an update on that truck crash here in Nashville which occurred one week ago today. The article in the posted link states 3 seperate times that the semi which was struck was transporting corn starch. I guess the tanker-style I saw on the news can indeed be used for transporting goods other than fuel.
On a sad note, the 2 deaths resulting from that crash were a decorated veteran of the Afghan war who was set to retire, and his young daughter. His wife is still critically injured and his son is still hospitalized as well.
I hope you are doing better soon LC.
Take it easy.
