One rendering (right) suggests a potential set-up, using a parking lot.
The challenge in Brooklyn: there isn't any obvious space, whether it for one bus, or five, or even more.
Can they put a bus on the arena plaza? Doubtful. The parking lot? Perhaps. Pacific Street? Unlikely. Private Fort Greene Place between the two malls? Who knows.
But any solution seems an awkward fit. Stay tuned; at least they have more time to prepare than with the Justin Bieber concert, where fans caused chaos on residential Dean Street.
