Thanks to Joshua Dyer at Harvest Noir for the post suggestion.

Harvest Noir is part evening out, part urban gathering and part celebration of local food. The dress-up, pop-up picnic and dance party (in a surprise location every year) happens in September, but the people behind Harvest Noir are holding a few events between now and then.
The first is a Summer Picnic at the Main Street Farmer’s Market on Saturday July 12, 2014. The “Parisian-style,” casual event is from noon to 3 p.m., and it’s free. Bring your own food (and blanket), or pick up picnic fare at the Market.
There’ll be another Summer Picnic on August 23 (location to be announced).
Harvest Noir raises funds for BioRegional North America, an Ottawa-based environmental organization.
