do it on the weekend where you can make several runs in one day with the ten mile round trip, and only make the 40 mile round trip once. cut and prep everything on a sunday when the yard isnt open so you can get as many quick runs in as possible while you're in the neighborhood. im assuming from the way you said it that the scrap yard is close to your family salvage yard, and not close to your house.

you and i share a lot in common, i know what it is to get up so early to hit the scales and then polish up for the office work, only to change clothes again and hit the scrap all over again at night and on the weekends. its tough and i lose sleep, but you'll figure it out. thank god i dont have to work inside, i have outdoor storage behind my 2nd floor one bedroom apt.
