Don't laugh. It's true: Arvada, Colorado, is the world's largest producer of crispy, crunchy celery. Incorporated back in 1904, Arvada has been an agricultural hotspot since then, especially when it comes to growing stalks of delicious celery. Though celery has been earning the people of this town a steady income for over a century, it was gold that first put Arvada on the map. This precious mineral was found in the Rockies in the mid-1800s, sending legions of eager prospectors scurrying West in search of it. You won't have to fight it out to stake your claim in Arvada today; all you'll have to do is track down a great apartment and sign the lease. What a relief that is!
