As the San Francisco Zoo prepares to reopen after a deadly tiger escape, officials are worried visitors won't feel secure.
With the criminal investigation into the fatal mauling of a 17-year-old boy on Christmas nearly complete, the zoo is to reopen on Thursday.
And previous zoo and aquarium disasters suggest that curiosity might actually draw people in.
A spokeswoman says attendance at the Aquarium of the Americas in New Orleans wasn't hurt in the weeks after a walkway collapsed and ten people fell into a 400,000-gallon shark tank in 2002.
No one was seriously hurt in the collapse, but she says people have "a bit of morbid curiosity" when it comes to seeing where an accident took place.
San Francisco zoo officials haven't said when the big cat enclosure will reopen.
