Check-in and registration opens at 3pm. If you arrive before that time, hang out in town or on campus and enjoy yourself. You will probably be able to drop your luggage off if you need to, but DENSI registration won't begin until 3.
When you register, make sure you have your less than $5 gift that you will bestow upon another attendee. We will collect them from you when you check-in and bring them to the barbecue. We will put them in a gift bag for you so keep it small-ish. Remember, people are flying home. (Gag gifts are discouraged. We want you to be able to share something about your home state/province.)
Bring your postcard from your hometown/state/province.
