My kids are still little (6&7) so my husband and I take them trick or treating every year. For the second year in a row they'll be Bumblebee and Ironman (of course I didn't know that before I donated last years costumes
)
We always end up 2 streets down from our building where the whole street gets decorated for halloween. It's very well done, and the kids love it.
Ususally after the kids are done gorging themselves on candy and are in bed, my husband and I curl up on the couch to watch Halloween (used to be the original, but now we watch the Rob Zombie version) or some other scary movie.
