Where to get scrap insulation foam?

[RobertInOntario]

I saw the answer to my question bouncing around in the wind today, in a driveway across from my work. An approx. 3x3' piece of white foam was being blown across a driveway near my office! So I quickly picked it up and stuffed it in the car. It might just be what I need to add a fiddle yard to my layout, although it's a little scuffed up & messy (so it might still be better to buy a new piece). At any rate, the scavenger in me is coming out and I feel a little chuffed that I found something that just might work for free!

My wife rolled her eyes though!
