For Saturday, there is ample parking available — the event is in Science Hall (“N” on the map), convenient to lots 14, 15, and 16, as well as street parking on Main or the athletic center lots 17 and 19. Attendees can park in any lot, permit not required.
If you prefer public transit, there are Metro Rail stops at Main-Humboldt and Delevan-Canisius that are also a short walk from Science Hall, as well as bicycle racks outside of the building.
Also, just a note, I know that lot 16 is a parking garage on the map, it’s been replaced with a surface lot and the map hasn’t been updated yet.
