Burnham, when I was a kid I used to go nuts from a half a day's tractor driving.  Then after while I got a satellite radio.  That helped pretty well. 
Anymore I dont even listen to the radio.  All day long I am trying to solve problems.  My mind is whirring around all day long.  Weather, prices, marketing, costs, plans, tactics, kids, family, life......you name it.
They say when you have a big decision to make or a problem to solve you should sleep on it.  I dont sleep worth a shit.  
I dont sleep on it.....I farm on it.
