Today is 7/11, which means 7-Eleven gives out out free 7.11-ounce Slurpees from 11am-7pm (wocka wocka). You get your choice of flavor, which sounds way better than when they were giving out those gross-sounding Slurpee Lites a few months ago. In Brooklyn, you can find a 7-Eleven on Flatbush Ave. near Fort Greene, in South Slope, Sheepshead Bay, Crown Heights or a few other places in Manhattan. The cups, sadly, are not as cool as they used to be in that photo above.
Completely off-topic, but the Bing map the 7-Eleven locator lists BoCoCa as an actual neighborhood. BIIIING!!! [shakes fist]
