Amanda, these guidelines look great. As a physician I think they are well thought out. Specifically I agree with masks being recommended but not required. One suggestion I might recommend for consideration is allowing refunds if handlers are not feeling well. We want people to be smart and avoid potential exposure to others if they might be coming down with covid. It is hard enough to give up on the fun of being at a trial but when you add a financial hit to that, some people may be hesitant to stay home when they really should. Just an idea... Cheryl
