=yeah The shelling is better in Florida or the outer banks of N.C.
I collect sand. I scoop a little of it up and put it in a plastic 35mm film container (2 for each beach). When I get home I put it on a cookie sheet and bake it on low heat to dry it out. Then I pour it in to a plain glass salt or pepper shaker which can be purchased really cheaply at the dollar store. I seal the top with some plastic wrap and trim the edges around the screw on top so the sand won't pour out. Then I label the shaker with the island i got the sand from.
It is interesting to see all the sand next to each other. The sand from Cozumel is a little finer than the sand from Grand Cayman. Sand from Costa Maya is about the same as Grand Cayman but has some flecks of pink in it. Sand from St. Thomas is much finer and a little more brown than the whiter sand from the Western Caribbean.
