This Sunday, 20 June, head to Lepelenburg Park in Utrecht for the first crowd-sourced Twitter Picnic. From 1 p.m. until 7 p.m., you can meet up with your fellow Twitter users and enjoy a social afternoon. Bring your favorite food and drink and enjoy music performed by various artists who feel inspired to perform. The whole event is what you make of it, so make the most of it in a beautiful setting. You can find some more information about the event and its organizers here (in Dutch).
