No trip to the beach is complete without a little souvenir scavenging. Namely, "shelling," or looking for seashells. There's something so wholesomely satisfying about finding a nice sand dollar, gently cleaning it off, and bringing it home as a memento of those beachy vibes. One of the best spots on Earth for shelling is a perhaps unsuspecting spot in Florida. Prepare to do the "Sanibel stoop."
