Hi,
I respect every ones oppinion, as farest I can said about the subject and this is just my oppinion, this is what I do:
I love music, so I take with me my accustic guitar, and my electronic key board, yes, I do have some other ways of entretainment on my truck, but if I play muy string instrument or my key board, I get far away of current problems and frustrations, it set me free of worries, tentions, dissapoinments and frustrations, it is a new world arround me, and I have to be playing them low, otherwise I will miss the c-link beep or the cell phone call (lol), this is what works for me, will it work for all of you? of course not, after all every one's life is a different world. And remember that no one is wrong, it is a matter of different oppinions.
Regards to all of you, and do not forget the main priciple. Be safe on your trips, have a faine ride and a safe one. JMHO.
SEMPER FI!!!!
