For all you blowhards! … Just joking. But, did you know that — just as there is the “tomb of the inflatable pig” in Paraguay, there are inflatable bras, and numerous other inflatable unmentionables — there’s also innovation in how you can inflate your tires?

And it turns out that — it figures that a “blue” company would be hip to this — COSTCO puts nitrogen in the tires of its customers!
