Just-because is the occasion Alexandria is actually built for, because the city is small enough that the people you would send flowers to for no reason mostly live within three miles of you. The everyday routes are neighborhood routes. Del Ray (22301) runs along Mount Vernon Avenue — the stretch locals just call The Avenue, home to First Thursday in the warm months, Art on the Avenue every October and a Halloween parade that shuts the street down — and it is a genuinely dog-heavy, porch-heavy, know-your-neighbors grid where a vase left on a covered front porch is safe and expected. Rosemont, North Ridge and Beverley Hills (22302) sit just uphill with the same bungalow-and-four-square housing stock and the same front steps. Old Town (22314) is the exception on this map rather than the rule: attached brick rowhouses with the door on the sidewalk, no setback, metered parking on King, Royal, Pitt, Fairfax and Union, cobblestone on the 100 block of Prince Street, and Market Square at the top of King hosting the farmers market that has operated continuously since 1753 — the oldest in the country — every Saturday morning. West of Quaker Lane, Seminary Hill, Cameron Station and the West End (22304 and 22311) mix garden apartments, townhouse clusters and the Landmark site now being rebuilt as West End Alexandria, with Bradlee Shopping Center at King Street and Quaker Lane as the neighborhood anchor. Arlandria and Potomac Yard (22305) run from the Chirilagua blocks up to the Metro station opened in 2023, Huntington (22303) and Kingstowne (22315) sit south of the Beltway around their own town center, and the Mount Vernon corridor (22306 through 22309) stretches down the parkway toward Belle Haven, Hollin Hills and Fort Hunt. What ties those routes together on foot is the trail network rather than the road network. The Mount Vernon Trail runs the full eastern edge of the city along the Potomac, Four Mile Run marks the Arlington boundary up at Arlandria, and the Holmes Run and Cameron Run greenways cut west through Seminary Hill toward the Beltway — which is a large part of why Del Ray in particular is the most dog-dense, most pedestrian, most likely-to-know-your-neighbor grid in the city, and why a just-because bouquet there is as often for the person who walked your dog as for anyone you are related to. Transit shapes the rest: seven Metro stations touch Alexandria at King Street-Old Town, Braddock Road, Eisenhower Avenue, Van Dorn Street, Huntington, Potomac Yard and Franconia-Springfield, and Amtrak and VRE call at Alexandria Union Station on Callahan Drive. Everyday errands cluster at Bradlee, Potomac Yard Shopping Center, Hoffman Town Center and Kingstowne Town Center, which is a useful way to picture where a recipient's afternoon actually goes.
