This weekend in Arcata, CA

Hosted by Humboldt Grange #501, this community breakfast welcomes neighbors in south Eureka. The menu features two styles of scrambled eggs with a choice of pancakes or biscuits and gravy, plus sausage. Beverages include coffee, tea, hot chocolate, and juice. Suggested donations are $10 for a large plate and $7 for a small plate, and children under 5 eat for free. This is a community service effort with volunteer opportunities, including early and late shifts. For details or to volunteer, call 707-442-4890.

Clean out your closet and discover new-to-you pieces at a clothing swap and Halloween costume event. You may bring up to one bag or box of clothes, and you can take as much as you like. Bringing items is not required to participate, so you can still take what you want even if you do not bring anything. Please do not bring kids clothing, socks, undergarments, or items that are dirty or damaged. Halloween costumes of any size, from infant to adult, are included.

The Undercovers deliver a high-energy set of danceable covers from a four-piece lineup of multi-instrumentalists who came together in 2014 to create a different kind of cover band for listeners of all ages. Their show moves across decades and genres with ease, shifting from AC/DC and Led Zeppelin to Bruno Mars and Notorious B.I.G., all with a vibrant spark that keeps the momentum going. Expect a broad mix that feels fresh, inclusive, and far from a traditional cover act.
