Clothing/Shoes/Weather Gear: If your into scavaging through the remains of what was left when the tide was out I recomend sandles. The reson being that if you wear aquasocks the wet ground sucks them up like quicksand and your foot gets stuck. Then when you pull your foot out you lose your sock, all gone, by-by, it's crab property now. if you have sandles with straps around your foot they won't be pulled off, plus its easier to get all of the rocks out too.
Photo Equipment: Don't forget your camera, film and other supplies. You may never be back here again, so take a picture.
