A horse trainer takes his horse into the water at Pebble Beach on June 28, 2024 in Bridgetown, Barbados. The swimming horses of Barbados offer a unique and remarkable experience at Pebbles Beach, where racehorses from the nearby Garrison Savannah enjoy their morning swim almost daily between 5:30 am and 7 am. During this ritual, horses swim out surprisingly far to the moored boats before returning to shore, with some staying longer in the water if recovering from injury or soreness after a race. Visitors can observe the horses' individual personalities as they swim and interact with the water, but are advised to respect the guidance of the grooms and maintain a safe distance, as horses can behave unpredictably, especially if frightened.

Everyone wants to get something for nothing - whether it's a lucky upgrade that means you can turn left when you get on a plane instead or heading off into the economy seats, or even getting a few extra features thrown in for free when you buy a new car.

As some of the sharpest businesses around, no-one understands this quite as well as casinos and that's why they all have a system that they call comps. It's short for "complimentary offers" and these are special treats specially designed to reward you for your loyalty to the casino in question. They're basically bonuses.
