The small town of Pisté welcomed the spring by having a big street fair. One of the main streets in town was shut down, and tents were put up - there were vendors selling wares, food stalls with delicious (and cheap!) fare, and a stage for live music. Many of the locals came dressed in traditional Mayan clothes (not just the older ladies, who are more likely to wear them day-to-day), and all the handmade goods from hammocks to tunkul drums were absolutely phenomenal.
The festival lasted three nights in a row, one day before and one day after the spring equinox as well as the equinox itself. Great times!
