To find a local SCA (Society for Creative Anachronism) group, you can visit the official SCA website and use their search feature for local branches or kingdoms near your area. You can also search on social media platforms, such as Facebook, for SCA-related groups or events in your region. Additionally, attending Renaissance fairs or historical reenactment events may connect you with local SCA enthusiasts.
