That's the slogan of the city of Downey. The city was founded in 1873, but not incorporated until 1956.
And to think I learned all that just by studying the city seal today on the chain-link fence at Independence Park...
Interestingly, that McDonalds sign on Lakewood pre-dates the city's incorporation. This means that when the neon "Speedee" sign rose up over Lakewood Boulevard, it was under the jurisdiction of Los Angeles County, and Downey was just an unincorporated town.
