Who Controls Trick or Treat?

I always just assumed that Trick or Treating was something that just happened, not something that was organized by someone. Well, according to the Boston Globe, many communities around Boston are cancelling or postponing Trick or Treating due to the damage wrought by this weekend's snowstorm (at least 500,000 houses were without power as of 9:00 this morning).

Something tells me the older kiddos will be outside regardless of what their local governments say. Regardless, i'm happy my town's festivities are not on the list - i'll be putting on my vampire makeup shortly after 5:00 PM!
