Big dogs and thick brush myth

Well...my grandfather and grandmother road a wagon behind mules or horses 12 miles to town and my dad his fine horse alongside...by the late 40s my dad purchased motor vehicles for getting back and forth to the farm/ranch...did all that after WW2...the mules went by the wayside and tractors replaced them...we evolve according to the new technology at hand...

I Remember the first computers at work...the boss said he was going to air condition the place for us...found out later computers need cool air for the electronics and of course low humidity...a win win...no more fighting mosquitoes...about that microwave ovens hit the scene...and Mobil phones soon after and they weighed about ten pounds...

And where I grew up it was mostly brush country and I could run my dogs any direction from the doorstep...and now it is cleared farmland as far as you can see...
