This is not just another pre-Derby neighborhood block party. This one will have bands, The Flea Off Market, games, vendors, beer and food. Plus, it is in Schnitzelburg, so you may be able to walk there. Wear orange to celebrate King’s Day, a national holiday in the Netherlands. The Flea Off Market lasts from 11 a.m. to 6 p.m. The bands, including The Kids Born Wrong and Tall Squares, play from 6 to 11 p.m.
