This just in, from the Wesleyan homepage:
Because of the appearance of Senator Obama at this year’s Commencement the event will be ticketed and there will be limited seating. Graduates will receive a limited number of tickets for their families, and will receive first preference on seating.
Because of the high amount of traffic that is anticipated, there will be no guarantee of any parking availability for this event.
We ask the general public to respect the ceremony, our graduates and their families during this event.
Glass bottles, fireworks, and selected other items will not be allowed at the ceremony. Anyone in possession of such items will be subject to removal and possible arrest.
