For over four decades, the Tri-Cities of eastern Washington have played host to "Water Racing's Greatest Show," the Unlimited hydroplanes.

Since 1966, the Unlimiteds have occupied center stage as the headline event for the annual Tri-City Water Follies celebration. The race was called the Atomic Cup in the early days but was renamed the Columbia Cup in 1976. Lamb-Weston came on board as title sponsor in 2007.
