Looks like lovely weather for the kick-off to the second annual Summer Streets tomorrow! Starting at 7 a.m., the city will temporarily close Park Avenue and connecting streets from the Brooklyn Bridge to Central Park, displacing motor vehicles and welcoming pedestrians, cyclists, joggers, skateboarders and other non-combustion engine participants. Penny farthing, anyone?

The DOT will provide 150 free bikes and 180 pairs of free skates tomorrow, and kick things off with a "Fun Run"—yes, a Fun Run!—at Foley Square at 7:30 a.m. The streets will reopen to motor vehicles at 1 p.m., but the whole thing will be repeated on the 15th and the 22nd. Map of the route, plus details on free bikes and other events are all here. And here's a look back at last year's inaugural Summer Streets.
