Reunion Weekend at Spring Carnival
Reunion Weekend celebrates friends new and old at exclusive events and opportunities during Spring Carnival, while attendees also enjoy treasured traditions like Buggy, Mobot, Midway and Booth.
This year, we were excited to welcome back undergraduate classes ending in 0s and 5s, as well as the Class of 2024. Every year, Half Century Tartans (Classes of 1974 and prior) are invited to attend reunion events.
