This 2017 photo released by Charles Fremont shows a home decorated for Halloween in Webster Groves, Mo. On a typical Halloween in the St. Louis suburb, neighbors go all out to decorate their houses and yards with spooky skeletons, tombstones and jack-o’-lanterns as up to 1,000 people pack the blocked-off street to carry on an old tradition: Tell a joke, get a treat. This Halloween is going to be vastly different for many. Parents and governments are weighing whether door-to-door trick-or-treating can safely happen. (Charles Fremont via AP)

NEW YORK — Roving grown-ups tossing candy at kids waiting on lawns. Drive-thru Halloween haunts. Yard parties instead of block parties and parades. Wider paths through corn mazes.
