Good topic. I have kids from 11 to 27 -- this is a timely discussion in our home. They want badly to go out and I won't let them. We're having a party, going to let them decorate, dress up and spook the older kids who come by.
But we're focusing on serving the little ones in our area. The house is big enough to have an "entrance" for the big teenagers -- they're calling it the Tunnel of Doom -- and we have a separate one for Happy Ghosts, where the little ones will feel welcomed.
But as for going door to door -- no.
