I hate sparklers for just that reason. People give them to kids, kids run around with them in the dark, and then drop the hot wires who knows where (at least the wooden ones are a little better) but everybody things they are so tame. They really are not, they burn like crazy. They require just as much caution as any other firework.
Oddly enough, NJ has gone the other way. In NJ you never were able to buy anything - no sparklers, no snakes, not even those snap pops you throw - all illegal. Last year they changed the law to allow the above, and even some ground effect fountains and such (sort of like PA used to be)
