Dec 25-26, 2012 Snow, Ice, Storms, OK, TX, MO, AR, LA, MS, AL

Big pile-up in OKC this morning on i-40 on an overpass. Even with the crews treating the roads, got to use extra caution on the bridges and overpasses. Probably a four-wheeler caused it. It's mainly just an ice event now with snow expected later in the day.

 

sure is raining hard at the pilot in anna tx

 

I left with my load and decided not to go home with it, but straight down to Houston area over the weekend. Spending Christmas in Houston area and delivering west of the city on Wednesday.

Homeward bound, but someone has stuck a storm between Houston and central Illinois.

Had enough of the white stuff last week when I went to Langley BC. and back.
