Des Moines Register: Starting Friday, customers entering the venerable East Village bar Blazing Saddle will be required to show proof they’ve been fully vaccinated against COVID-19 or that they’ve tested negative for the virus in the last 48 hours. Though the requirement is common at bars and restaurants in other parts of the U.S., it apparently is a first for Des Moines, though the Indianola-based Des Moines Metro Opera has a similar policy.
