North Charleston Mayor Keith Summey, right, talked last year with a vendor at the North Charleston Business Expo, which returns Thursday as the Lowcountry’s largest business-to-business event,. The Expo, which will be held from 1 p.m. to 4:30 p.m. at the Charleston Area Convention Center, will showcase 175 area organizations and businesses. The event, now in its third year, is free. A networking reception will follow from 4:30 p.m. to 6 p.m. There’s also a luncheon earlier with area mayors and leaders, but registration is required.
