Thanks for the tip!
Just wanted to say thanks for the heads up about the sargassum weed. Had I not been faithfully scouring the Sowal boards before our vacation, I wouldn't have thought to investigate for critters in the seaweed, and the kids would have really missed out. We found several lantern fish, crabs and other things, and we had quite the aquarium going in our sand bucket every day.
We also managed to find hamburger beans and sea hearts washed up in the seaweed, too - two collectible things beachhounds will probably recognize. I've been surprisingly successful in all my previous trips at finding some really great shells -- lots of scotch bonnets, chestnut turbans, olives, moons, etc. -- but the sea beans were a treat because I'd never scrounged for those before, and the sargassum is a great place to find them.
Oh, and for those of you who love beachcombing as much as I do, I can highly recommend two books - Florida's Living Beaches and Florida Seashells. They're a wealth of info about whatever you might find washed up on the shore. I'd consider them a must if I were a resident...
Thanks again!
