here in Cah Lee Fuh Nee Ah there are 'sound walls' that are decorated with all kinds of stuff...In Orange County near San Juan Capistrano they have a wall with birds on it-near Dizzyland they have some ugly blue tiles that look like they belong under pots in a kitchen.

On the new 210 Freeway near San Bernardino they have fake rocks that are done in a wave pattern.

I like the palms......
