LISSE, Netherlands (AP) — Thousands of visitors have tiptoed through millions of tulips and other flowers in an iconic Dutch spring garden as part of a government pilot scheme to evaluate how to reopen public venues. A maximum of 5,000 visitors were allowed Friday into the Keukenhof garden if they could show proof on a smartphone app that they had just tested negative for COVID-19. Minke Klein visited with a friend and said it felt like their first “legal day out” amid a months-long coronavirus lockdown in the Netherlands. The friends took rapid tests before setting off and got their negative results by email as they drove.
