Per the LUNGS website:
The parade will begin at noon at El Sol Brillante, 12th Street between Avenue A and Avenue B, meander down Avenue C ... cross 6th Street and end up on Avenue B.
Spring Awakening will feature a photo scavenger-treasure hunt, prizes, music, puppets, workshops, comedy and art.
Some of the individual community gardens will be hosting events throughout the afternoon. Check this link for details.
There will also be events in the afternoon on Avenue B between Eighth Street and Ninth Street in conjunction with Loisaida Open Streets. (Yesterday, City Council made the Open Streets program permanent. More on this later.)
