Unless my Mac dashboard weather widget is deceiving me (and it’s been known to), tomorrow should be a gorgeous day for the debut of Summer Streets 2009. Here’s a look back at last year’s fun, care of Streetfilms, to whet your appetite.

Earlier today, Lily Bernheimer posted a nice rundown of related goings-on tomorrow in the Livable Streets Community. And if you can make it, start the weekend off right this evening with a ride on the city’s newest cycling amenity, the Sands Street separated bike lane.

Enjoy.
