Here, Homecoming isn’t just a day, it’s an entire week. This year, Parents Weekend is just a part of the Homecoming festivities. On Oct. 18, Chancellor Mark S. Wrighton will talk about the undergraduate experience here as well as host several lunches and dinners for various groups; a tailgate party will start at 11 a.m.; and students will have several competitions. The big event of the weekend is, of course, the football game. This year, University Athletic Association rival University of Chicago will be in town for a noon kickoff at Francis Field. All other athletic teams are on the road this weekend.
