Good to know

Haunted houses sell out on the last two weekends — book ahead, don't walk up.
Pumpkin patches are best on weekday mornings: smaller crowds, better light for photos.
Bring cash for the farm stands; card readers and corn mazes don't always mix.
Check age guidance before bringing small kids to a haunt — 'family fright nights' are the gentler pick.
