Seattle is currently dealing with COVID 19. And what's allowed keeps changing. Recommended precautions such as wearing masks, maintaining social distances and doing stuff outdoors are good habits to stay safe. Masks are required when outdoors and 6 ft. physical distancing cannot be maintained. Good news is that the tour is outdoors and distances can be maintained and it's easy to put on a mask when needed. All bikes are sanitized between uses. Hand sanitizer for each bike is provided.
