My DDs 10 and 13 love the Boneyard! DD13's favorite thing to do at AK is dig up the 'buried' dinosaur fossil on the far side of the boneyard. Last trip she spent over an hour there, getting sand all over her. I thought at age 13 that she'd be over it by now, but she still loves to dig (future archaeologist (sp?)) - she digs big holes in the sand at the beach, looking for buried stuff.
