Customers and tenants alike complain about the tough parking situation at Mockingbird Station. Folks anxiously cruise the shops during peak hours, holding up the line of cars for minutes at a time while they wait for some 17-year-old to quit fumbling with her keys, get in her damned Audi and make her precious space available. It's not that there aren't enough parking spaces--there's underground parking on the east side of the shops and plenty of covered and adjacent spots to the north. But it just seems so far. Smart MS shoppers, though, know the secret. Go the service road on northbound Central Expressway, take it about 50 yards or so, then enter the near-secret covered lot that allows you to exit between Silver Moon and Virgin Megastore. When you're done, bam, you whip out onto the service road, no parking hassle at all. And parking is important to us, because we're old and cranky.
