Everything was yellow

How do I believe I'm not in a fairy tale? 

We stayed in the city of Izamal last night. All the buildings are turmeric yellow. It is all cobbled streets, colonial architecture. Curving narrow streets lined with yellow walls. Horses wear hats and pull brightly colored carriages across the cobbles. There is a magnificent stone pyramid built by the Mayans, which you can climb on. Funny little bike carts sell ice cream and corn on the cob. Young boys fly kites. Festive music wafts in the breeze. 

And it was amazing, because the tourists here were almost all Mexican people, so it felt undiscovered and especially precious. But mostly just yellow, a feast of yellow.
