Sussex Ray Sikora and the Sterling Mine Band will perform the second concert in the Friends of High Point State Park Summer Concert Series on Saturday, July 16, from 6 to 8 p.m. Sikora, a Sussex County entertainer, will be reuniting with some of his musician friends to boogie on the beach of Lake Marcia. It’s party music that will have audience members jumping out of their flip-flops. The concert series will conclude on Saturday, Aug. 20, with Kindred Spirit joining the summer concert lineup for the first time. Concert admission is free. Bring a blanket to spread out on the sand or lawn. In the event of rain, the concert will take place in the Interpretive Center. For more information visit www.friendshighpointstatepark.blogspot.com.
