I pose a different question...
Have you figured what is the environmental impact of the foam project?
The "saw dust" blowing into the woods where it will not break down for 350 years. How many earthworm will die because they can not crap out the foam? And die from intestinal distress???
What about the deer that may be scared to eat the grass near your car's construction site because they think your car is the ultra rare Golden Aero Bear and die of starvation?
No one cares about the little animals do they!!!???!!!
Oh the humanity!!!!
