Same thing happened at the Lancaster Quilt Show several years back. The quilts that fell like dominoes were the best-of-the-best, the ones that got all the prizes. This happened early in the day and when we returned later to see these quilts, they were still on the floor. As I recall the disaster was caused by a child in a stroller. I personally believe strollers and cargo carts should be banned particularly at a heavily attended show. Just me, but I have tripped over same too often.
