Boulder’s Rayback Collective, best known as the city’s food truck central, hosts another FREE Rayback Repair Day on Saturday, October 7, 10 a.m. to 1 p.m. Volunteer handy(wo)men who’ll help attendees learn how to fix assorted home items to get maximum use and keep them out of landfills. Bring such items as small appliances, basic electronics, small furniture, bicycles and toys. Saving money by DIY repairing rather than replacing can free up some cash to stick around while after you’ve completed your repair to enjoy a drink at the bar or lunch at one of those food trucks. 2775 Valmont Rd., Boulder, 303-214-2127.
