Just before we walked down an older man wearing jeans, shirt and brown straw hat in his 50ties walked towards us bare feet and offered a free tour. We looked at each other and agreed.
Cayman Blow hole: Is a cavern in the rock at shore where wave hits against shore and moves in the cavern and then in the sky as it does not have space where to escape. Blow holes can best be observed when sea is rough with big waves and with 20-30 ft high “Blows”
This bare feet man showed us old fossils of fish, snails and corals in the stones, that I would have noticed if he didn’t show them. Then he offered to take a snap of us at blow hole on the moment when it shoots for the sky. And he was off.
