Let’s say you’re already set for the West Seattle 5K tomorrow morning, benefiting WS High School students through the PTSA. You have another chance to get moving for a good cause later in the day – Sunday afternoon, it’s the Zumbathon benefit for Transitional Resources, sponsored by an array of local businesses to assist TR in its work helping people living with mental-health challenges. Get dancing 1-3 pm Sunday with instructors Jennifer Cepeda and Annie Stilts, inside the spacious West Seattle Christian Church Activity Center at 4400 42nd SW; registration info is here.
