Haha ya I love that stuff I went last year..it was fun didn't get bumped into but I will deff look into getting that belly bumper..thanks :)
I've heard from a few people it's pretty chaotic and people bumping into each other, you have to be careful people running into you for reasons of placental abruption, definitely no rides though. You can get a belly bumper, it's like a wrap that protects your uterus from bumps in crowded places, if that's something you'd want to look into. I wouldn't risk it, but I'm also terrified of scary stuff, haha!
