Some beaches prohibit taking driftwood but others have no policy. If taking driftwood from a beach, be cognoscente of the environment - don't take too much as to disturb the beach and ensure you obey the laws. Also make sure you dry the wood thoroughly and leave any critters that might be inhabiting the wood back at the beach.
This alligator is a wonderful piece found in a great green home I had the privileged of touring.
These horses by Heather Jansch are also very impressive.
