Where to get scrap insulation foam?

Thanks, Andrew. I like the idea of trying the local big box stores. But I'm not sure what my wife would think if I started picking up scraps along the highway, although that would work too! I'll have to do this when I'm on my own!
Cheers,
Rob

Why?...I do it all the time.
You know how much of that pink stuff blows off flatbeds on the highway.

I don't recall seeing any of the pink stuff along roadways but then I haven't been looking! I'll keep my eyes open & see what I can find.
