Santa Barbara's Greyhound Bus station has a classic neon sign. Unfortunately, the neon hasn't worked in years. Greyhound wants to sell this building and move to another one. As of this time I don't know the fate of this building.
UPDATE, November, 2008: No changes yet, still in business as the Greyhound station.
UPDATE #2, August, 2009: Still operating as a Greyhound station.
UPDATE #3, December, 2009: The bus station has downsized and half the building now belongs to an art gallery, half is still the Greyhound station.
UPDATE #4, March, 2012: The signs have been removed and Greyhound has moved to their new location.
