the wife- maps-travel-GPS cell

So we have to leave tomorrow on a 6 hr trip to Corpus Christi to pickup 3 Boer goats. I pull up mapquest for their route as her "country" route makes me dizzy pulling a triler and I ain't getting on a Texas Intereste on thos holiday. No I ain't driving 3 hrs out of the way to stop at Buc ee's!
We always have trouble traveling as she is in change of the GPS on her cell, reading roadmaps, etc.. I sure try to keep a cool head, but.....
I am trying to explain the suggested new route, and when she tells me I am holding the MAP SIDEDOWN!!!!!!! ( No it is NOT!!)
I know I am screwed again!!!!!

12-14 hours on the road, an over nighter, pulling the little goat trailer with a friggin Toyota whatever it is!!!!! God help me PLEASE!!!
