CALGARY Fans of dinosaurs and their suspected bathroom habits and escape rooms are in luck as the Calgary Zoo has unveiled some of its plans to attract visitors amidst the pandemic. This year will see the return of Locked Zoo, a large zoo-wide escape experience similar to escape rooms that proved popular in 2020. The Locked Zoo concept had been an idea book for a very long time and the special experiences team figured out how we could do it, said Alison Archambault, Calgary Zoo s brand and engagement director. Then they worked with Alberta Health Services to ensure that what we were proposing was safe.
