I came across this and had to share. I probably won't find one at a garage sale up here, but it's definitely on my "scrounge list."

There's a goo-tube link on the web page. The dude that posted this actually opened the can! Interesting, but I would have been inclined to keep it as an artifact. How many of these, unopened, can there be left?

BTW, out of curiosity, what's on your "scrounge list?"
