Wondered why my entire 'hood smelled like pot during my run. Then I remembered that @furthurband is playing @ the Barclays Center tonight 😛I take it the pot was being smoked before the show on the nearby streets, as was the case before a couple of the Jay-Z shows last fall.

Some people prepared (pre-gamed?) otherwise, as indicated in the first of several photos sent to me.
Others turned the plaza into a bit of a barbecue scene.
A notably large number of people brought their dogs and--as I heard secondhand but haven't confirmed--a good number were designated service dogs and thus could have been able to get into the arena.
Others engaged in creative calls for support.
