Machine #1 is located to the left of the entrance of the Grasslands Cafe facing the elephant exhibit.
Machine #2 is located on the right corner of the Asian Discovery Center facing the elephant exhibit.
Both machines are literally in sight of one another and work great.
Machine #2 has been moved. The Zoo has a new entrance / ticket window. The machine is near the Zoo entrance on the opposite side of the ticket window. Easy to find when leaving Zoo because the machine is next to the Zoo map recycling station.
