The second thing to know is where El Monte birthday flowers are actually going, because it is rarely a tower lobby. Longo Toyota at 3534 N Peck Rd is the biggest-volume Toyota dealership in the country and sells and services cars across a sales floor, a service drive, a parts counter and a body shop, with Lexus of El Monte on the same campus — which means "Longo" on its own is not a delivery address. Name the department and give a mobile number, because a service advisor is standing outdoors next to a car, not sitting near a receptionist. The same rule, harder, applies across the South El Monte industrial district just south of the 10 — the blocks off Rush Street, Peck Road and Santa Anita Avenue hold a remarkable density of small manufacturers, machine shops, printers and food plants, most of them a roll-up door with a two-desk front office and a bell. A suite number and a cell phone turn that into a first-attempt delivery; "the warehouse on Rush" does not. The mid-rise exception is the Flair Drive cluster off Santa Anita at the freeway, El Monte's only real office-building address, where the suite number is the whole game. Add El Monte City Hall at 11333 Valley Blvd and the school district offices, and you have most of the city's weekday desk drops.
Residential El Monte is friendlier to a driver than most of Los Angeles County, and worth understanding before you order. The city is compact — under ten square miles — with 91731 covering the western and downtown side around Valley Boulevard and 91732 the larger eastern half; 91733 is the separate city of South El Monte; and 91734 and 91735 exist only as post-office boxes, so a bouquet cannot be sent to one. The Rio Hondo on the west and the San Gabriel River on the east cut the grid into strips, and a house that looks close on a map may need the bridge at Peck, Durfee, Santa Anita, Lower Azusa or Valley, which is worth ten minutes on a Friday afternoon. What works in your favour: apartment courts along Garvey and Valley, mobile-home parks where a space number is the address, rear units behind main houses, and a lot of multi-generational households where someone genuinely is home at two in the afternoon. Up in North El Monte above Lower Azusa the lots get large and a few still keep horses, so give the gate detail. And when the party is a weekend carne asada at Legg Lake in the Whittier Narrows Recreation Area, remember the park has no street address a driver can deliver to — send the flowers to the house that morning and let them travel with the ice chests.
