we found the entire remnants of a horseshoe crab at the beach. i was surprised because usually i only come across bits and pieces or tails. patrick spent a lot of time digging for sand crabs (or mole crabs) and collecting shells and stones to mix in with the soil for our new cacti. i spent most of the day in and out of the water. i like watching the mussels burrow back into the sand when the waves go out.
