In The loop

There are few better ways to break up Tuesday than to spend it underwater, metaphorically. The Shedd’s Illinois Resident Free Night lets you wander through its exhibits without paying regular admission.

Where: Shedd Aquarium, 1200 S. DuSable Lake Shore Dr., Chicago
When: Tuesday, Oct. 27, 5–9 p.m.
Cost: Free for Illinois residents with valid ID
Reserve: Online: $5 convenience fee per order; phone: 312-939-2438, no convenience fee

Reserve ahead because walk-up availability is limited. The seasonal Stingray Touch experience is included when operating; other add-ons may cost extra.
