Here in (hot) Arizona, a few zoos wisely decided to start opening at night on select days during the summer. The famous San Diego Zoo also does this. And Singapore Zoo opened a separate night only wildlife park called Night Safari. I will kick things off, but I would love to see some other photos taken at zoos and wildlife parks during evening hours. On two of these (porcupine and screamer/capybara) I used a small LED pocket flashlight to highlight the animals. All with 5D2.
