Starting last Friday, museums, aquariums, and zoos in Iowa were allowed to reopen at full capacity, and at least one venue said it experienced an increase in traffic over the weekend. The National Mississippi River Museum & Aquarium in Dubuque says its staff and animals were glad to have more visitors back after reopening at 50% capacity two weeks ago. Until then, the museum had been closed more than two months because of the coronavirus. Museum Store Manager Mark Girardy tells KCRG TV they have markers on the floor to encourage groups to space themselves apart, and staff said they’re frequently cleaning and wiping down the areas of the museum that people like to touch. In the two weeks it had been limited to 50% capacity, the museum had used a timed entry system to limit how many people could come in each half-hour, but Girardy said they never had to turn anyone away.
