We have recently updated our safety policies based on revised CDC guidelines. According to the information on the CDC website "If you are fully vaccinated, you can resume activities that you did prior to the pandemic. Fully vaccinated people can resume activities without wearing a mask or physically distancing, except where required by federal, state, local, tribal, or territorial laws, rules, and regulations, including local business and workplace guidance. If you haven’t been vaccinated yet, find a vaccine."If you are not vaccinated or have additional health concerns we would still recommend wearing a mask.
