You will most likely have to go in the side door, which has card access. If you don't have a DukeCard, you can either lurk by the side door and follow someone in, or just pound on the front door until someone hears you :). We'll most likely be checking the doors to help people find the meeting place before 7:00 PM, so if you're unsure, just come a bit early and we'll make sure you get in.
