Arcadia, about 20 miles from downtown Los Angeles, has some of the best schools in California. It is also home to Santa Anita Park racetrack and the Los Angeles County Arboretum & Botanic Garden. Peacocks now live in the neighborhood near the arboretum where they walk on lawns or cross the street and, for some, are a bit of a nuisance.
