Brent sez, "'Think Spring, Boing Boing Boing' is presently displayed on the Flying Pie Pizzaria marquee in Boise, Idaho. I do not believe this was in any way a reference to Boing Boing, but I thought you might enjoy it.
I have no affiliation with them (though they are a great local chain and their pizza and beer selection is outstanding)."
(Thanks, Brent!)
