Plenty? No. A small minority? Sure. There's always someone on the edge of the fringe. If she had a history of mental problems and bad decisions, it would make more sense. But probably 95% of the women there were with someone. Women don't even go to the bathroom alone. People don't go to concerts alone. There wasn't one passionate family member or friend she felt like asking to go with her? And it seems suspect considering the other details, like being "buried" at sea. She wasn't in the navy. Did she have a passion about the ocean? It doesn't add up.
