Marin County health officials are going to ease restrictions for indoor mask wearing starting this Friday. Officials say people who can show proof of being fully vaccinated will be exempt in most indoor settings with fewer than 100 people. This includes gyms and fitness centers, office settings, religious gatherings, and college classes. Officials say this does not include indoor retail, bars and restaurants. Marin County residents, ages 12 and older, are 92% vaccinated, and 80% of the entire population is vaccinated.
