The BART train pulls to a stop after an atmospheric 20-minute ride, unloading the Warriors fans who made the trip under the San Francisco Bay, including a trio discussing the possibility of tossing their singlets in the harbour if Golden State lose.
It's been that kind of week. A 3-1 series lead has been chipped away by LeBron James and the Cavaliers and a second straight title suddenly seems in serious doubt.
But anticipation, rather than anxiety, is the prevailing sentiment. The Warriors, after all, have unarguably the better all-round team, and they're back at home, awaiting a sea of yellow that now packs the path en route to Oracle Arena, as a steady drumbeat emanating from cannily placed buskers provides what in hindsight proves a foreboding soundtrack for the short walk.
The odd flash of maroon dotted around the arena reveals the presence of the enemy: Cavaliers fans. While American supporters rarely travel in force, many Clevelanders have snatched the chance to watch their heroes snap a 52-year title drought for the city, with opportunistic locals happy to cash in and oblige that desperation.
Tickets on the secondary market, I had discovered, were easy to acquire. The day before the most-anticipated basketball game in 20 years, seats were being offered for no more than a mere pay cheque. Who could decline such a bargain, even if the view was three rows from the back in the uppermost corner of an 18,000-strong crowd?
