I've never had the pleasure. It must be delightful!
My late SO came home one day in the late 90's (from building a gulf front house at Inlet Beach) so excited because he'd seen 2 deer come bounding out of the dunes, race down to the beach, leap into the surf, and go for a swim! He'd never seen such a sight, despite a lifetime in Florida near the water.
I would LOVE to see deer on the beach..
