The tour buses that are everywhere are polluting the air and you can smell the exhaust and not the fresh air anywhere you go. You can t walk and feel you toddlers are safe because of the buses. Not to mention some animals looked so lethargic like the poor pandas! And before you get to them you encounter zoo employees that try to sell you pictures etc .. no surprise there because once we saw the pandas we were very sad and we didn t want to support them staying there.
