I live in Southern California and there's several events in the area that have haunted attractions. Example knotts berry farm gets converted to Knotts "Scary" Farm or "Halloween Horror Nights" at Universal Studios. We usually go yearly and I'm not one to get frightened. But we love going. I've put off going this year but now I'm wondering if it's ok? (I'm 21 weeks pregnant and barely have a bump). Nothing happens just a lot of walking and waiting in lines to get into the mazes.  Input please. TIA
