If you are ever in a place where you see mistreated work animals, like the horses we saw here, the best thing you can do is not support the people who make money off of them. These poor horses were skin and bones, sweating and probably extremely thirsty; waiting for stupid tourists to pay to see the city. This is cruel and inhumane. Giving these people your money does not help the animals get food, it just encourages these people to keep mistreating their four legged companions.
