Iron bubbles...don't those hurt when they land?

We had our grandson and two other small groups of kids, 2 with one adult and three with two adults and that was it. Hardly any of our neighbourhood had their lights on, so that was discouraging to them I am sure. It was really kind of sad. My brother always comes over to see them as he enjoys passing out the candy and seeing their costumes, etc. I wonder if we will ever get any in years to come. We turned off our lights at 8p and blew out the candle in the jack o'lantern. I thought it being on a Saturday there might be more. Seems a ton of kids went to some thing at the mall..I know it is safer, but I hate kids getting sucked into commerce for this, esp.
