Here is a video from JUST ADD SALTWATER, showing dolphins cavorting in the bow waves of a boat. Don't they look like they're just having a great time?
Here's the description from the video maker: Rocky Point/Puerto Penasco Mexico dolphins in the Sea of Cortez as seen from aboard CUATES with Captain Rick Hammer go to http://www.rockypointboattrips.com/
If this doesn't make you smile with delight (and wish you were there) there's something wrong with you. ;)
