The town of Progreso is a mix of fishing port, industrial port, and tourist destination with a population of about 45,000. The people are friendly and there is no area where you don't feel safe to walk any time day or night. There are more schools than bars and more recreation fields and playgrounds than I have seen in all of Sonora. I saw activities going on for kids every evening, especially in the central park, or zócalo.
The local band of kiters were the best I've ever met. Most were university students in Merida and could only get to the beach a couple of times a week. They weren't shy about trying out new moves as some had the hope of getting a sponsorship from a kite company. They were also the friendliest and most helpful group I've ever met. They truly treated me as a brother. I hope some of them can make it to San Carlos sometime; I have a spare bedroom for any of them to use.
