ATLANTA (AP) – The Dallas Zoo prepared for large crowds Tuesday during $1 admission day even as forecasters predicted triple-digit temperatures and issued a heat advisory. Zoo spokeswoman Chelsey Norris says a typical summer weekday would attract 2,000 guests. Norris says a Dallas Zoo dollar admission day in July drew more than 30,000 visitors, with temperatures in the 90s. Norris advised visitors Tuesday to be prepared for hot weather by using sunscreen and drinking lots of water. Misting tents were set up throughout the Dallas Zoo to provide visitors with another way to cool down. Norris says zoo personnel closely monitor the animals and move them to cooler indoor areas as needed. She says elephants would be soaked with water cannons and offered frozen ice treats.
