on your way up Calle Aleda Azcuy before you get to the baseball stadium, you will come to the very small Parke Prehistorico on your left. It sure is not the Museum of Natural History or the Smithsonian but it is classic Cuban. The proprietor, Jesus, has this rag tag collection of prehistoric artifacts and unique flora and fauna that he has personally collected, researched, and has created exhibits. He is the treat, not things in there. He is a self taught expert on everything there, a real tribute to the Cuban education system. He is so enthusiastic and proud that you will eventually find yourself making some excuse to leave so he will not consume your entire day.
Sadly "Senor Beisbol" who lived in a house on the right just past the baseball stadium recently passed away. He used to sit outside on his porch to talk to passersby. He would pull of his collection of baseball memorabilia, including his box of baseballs from Cuban national championship games, all having signatures of the players. Then you realize his signature was on every one of them. And he would show you his small collection of old baseball cards, every one having his photo and stats on it. Just an old guy who happened to be Cuba's equivalent of Mickey Mantle. But there are those kind of people all over Vinales.
There is the very colorful 97 year old pig farmer. But he is my secret and I don't tell people his name or where he lives. You have find your own but they are there in Vinales.
Just don't think the natural wonders are all there is to Vinales. There is so much more in the local residents.
