Apparently the CPSC has copied my Halloween tips idea.  Seriously though, they did issue a press release yesterday - much of it is similar to my tips below, but they offer some additional suggestions that are worth checking out.

Also, my 7 year old daughter, Jane, wanted me to say that in addition to the flashlights, they will be wearing blinking necklaces for visibility.  I'll let you know what luck I have getting her and her sister to wear a coat over their costumes if it's cold.
