cmon christ, surely you can attest to the "manufacturing" environmental impacts
not all rigs who carry the fuel run on bio, in fact a lot of them still use petro diesel
and the rigs are one of the main street-polluters
driving 60 miles for a free couch doesnt really mean free after all
now im not saying anything bad about bio, in fact i think its great
but i was paying around $4 for bio while i got veggie for free
so i was able to do a 50/50 blend on bio-veggie
$2/gallon FTW
