I have seen some great uses for seaweed on the beach. Instead of writing in the sand, people are making giant letters out of seaweed to spell out funny things- fun to see when you are standing up on one of the accesses. We also used to make sand people and the seaweed is the crazy hair and beards. Also, stand out in the water and pick up clumps of seaweed and look closely- there are sometimes critters hiding in there, like little fish and crabs.
Careful! The Society For the Prevention of Seaweed Abuse (SPSA) may read this.
