I agree with you completely. It is hard to conceive of a better situation than a coast with high and low tides and plenty of shellfish and kelp or other aquatic plants. In addition, there are all the items might find while beachcombing; I have found functioning flashlights, unopened soda cans, literally miles of rope and cordage, net floats (both glass and plastic) marine charts, - you name it, it will turn up on a each someday.
