If tickets are sold out, we do NOT sell tickets at the door. We understand the frustration of not being able to purchase a ticket, but we strive to make these events enjoyable for all attendees by keeping the attendance at a specific maximum number. When tickets for the upcoming Social Science sellout, tickets for the next Social Science event will go on sale, and we encourage you to purchase those tickets as soon as possible. Signing up for our e-newsletter is a great way to be in the know when tickets go on sale.
