In Seattle it can be challenging to remember the names of the east-to-west streets in the downtown core. The names are not alphabetized. Since they run in pairs, you only have to remember the basic order, which we do by this mnemonic. From south to north, they are
Jesus (James and Jefferson)
Christ (Columbia and Cherry)
Made (Madison and Marion)
Seattle (Seneca and Spring)
Under (Union and University)
Protest (Pike and Pine)

Now if someone could provide a decent one for Rainer/Renton/MLK Avenues in the south end I'd never get lost. I came up with
"Rainier, Renton, MLK, that is how you go west way." That's from east to west, I know it's lame, and since the Aves cross it's not completely true.
