Modesto's official slogan is "Water Wealth Contentment Health," which is emblazoned on a large arch uptown that has been immortalized in many photographs. A contest was run in 1911 to determine the slogan. The original winning slogan was: "Nobody's got Modesto's goat". The second place entry was the final winner.
That would about sum it up, except that the article also notes the Modesto is basically a crime-ridden commuter town. That, I think, does sum it up.
