Dandi Manuel won’t tell you how old she is.In fact, just asking is kind of rude – it’s the sort of thing that your Dad tells you when you’re old enough to steal dabs of his after shave.But she’s been baton twirling ever since she was a baby. And now she’s old enough to have a daughter that’s good enough at baton twirling herself to travel around the world and compete against some of the best competition that the sport has to offer.And that means that she has a lot of knowledge to pass on to those who participate in her annual Fourth of July baton twirling camp at the Manteca Library’s McFall Room starting on July 1.Those that sign-up – the camp will run through July 3 and all participants will get to march in the annual Fourth of July Parade down Main Street – typically use the experience as a launching point towards year-round classes. The best students move on to competing.
