Thank you, Bezzo. That's a great idea. I'm thinking a tower made from the Hirst Arts Turret mold sitting on a little Styrofoam hill should fill the bill. Maybe even with a ruined version.
I had inadvertently already made an island while setting up the table. I had a cd that I'd covered with Palm tree bases for ease of carrying the trees. It was sitting in the water while I was placing the rest of the scenery when my son saw it and said "Ooh, an island. I wonder if it has buried treasure." Gives me an idea for a scenario.
And thanks, Smokey, I have been visiting the Major General's site a lot lately. Being likened to them is a fine compliment.
