DSF just announced a pin trading event. No information now except for the date of Sunday, March 24th, 2019. The event page says the event location is at DSF, but this will probably be updated when more information is posted. I would assume this is the event they spoke of at the end of the Best Friends/WiR 2 trade event. They said the event will be Under the Big Top, so probably heavily or fully Dumbo (perhaps a mix of live action and animated).
