Being an Arizona resident, I've managed to visit all 5 of the state's AZA-accredited facilities at least once. While I think the ASDM is the best of them, I'm gonna let the rest of you vote among all 5 to see what you think.
These type of voting 'polls' are difficult when it comes to comparing zoos. Certainly Phoenix Zoo is a large facility that can easily take at least 5 hours to tour, with an extensive collection of ABC animals. However, ASDM is superb and full of high quality exhibits. My heart leans towards ASDM, but my head says Phoenix because if I had to choose to live next to only one of these zoos then Phoenix holds the greater appeal. I have visited both twice (not bad for a Canadian!) and I certainly know that my own 4 kids would choose Phoenix Zoo in a heartbeat.
