We're aiming to have the Wiknic this year on Saturday, July 11 at Blackburn Park. That's the same location as last year and it worked really well. Signups are here:

The scheduling has been pretty inefficient this year. I just took the most popular date from the other cities and then tried to correct. Next year I will just send out an email early asking people to list weekends in July that work for them, and I will pick the most popular one.
I hope to see you there!
