3. A locked-down tourism board is promoting vaccination instead
Australian Prime Minister Scott Morrison says anti-lockdown protesters are “selfish” for breaking social distancing rules.

9. Face masks will be needed in America’s national parks
An influx of visitors is forcing Arches National Park in Utah to temporarily shut its gates almost daily. And disappointed visitors aren’t the only consequence of overcrowding. The National Park Service is anticipating one of its busiest summers on record, so Arches won’t be the only popular park where crowds could be an issue. CNN’s Lucy Kafanov reports.
This applies regardless of your vaccination status or transmission levels within the community and the requirement will be in effect until further notice, the NPS said Monday.
