One Mile Down the Road...

 ...the check engine light comes on and the cab of the Penske began to shake and rattle.  Not good.  We decide, via walkie talkie, that we should pull off at the next exit (still with in Savannah City limits) and give the good people at Penske a call to have that investigated.
We waited in a gas station parking lot for a mechanic to come check out our issues which took about 45 minutes.  He ran the computer on the check engine light and came up with nothing but upon examination of the two front tires decided that we needed a switch out.  It just so happened that the Savannah area Penske Mechanic shop was 3 miles from where we were, convenient.  Another hour and a half later we were back on the interstate headed for Christmas in Mississippi.  Now 11:30ish.
