Green Lake should let bikes back on the main trail. I haven’t taken my bike there since the pandemic, but have walked around it a few times. It’s fine. But I never noticed a problem walking on the path pre pandemic. It made a certain amount of sense when we didn’t realize how much being outside helped curb the spread. But there’s no reason to keep bicycles off the path now.
Anyway, wash your hands right now, you filthy weirdo. And for goodness sake get vaccinated or boosted if you are eligible.
