I'm going tomorrow with my husband and boys ...in pretty sure it would be fine even in an enclosed arena because im sure they have to meet a certain code before they could do a show
Well, I don't think the baby's ears are developed yet, or I'd be worried about the noise, those events are noisy! The other problem is if it is in an enclosed arena, the place fills with exhaust and smoke. Even though you are still early in pregnancy, I would consider giving this year's show a pass.
