i put out about 15 pumpkins in the landscape, and more on the steps up to the front door. dark red mums in containers at the front door, a Halloween wreath my gf made for me last year, some 2.5'/4' tall metal ghosts are also here and there in the landscape.
on November 1, i'll remove any Halloween stuff, and replace with Fall/Thanksgiving items. ( a different wreath on the door, put the ghosts to bed, etc.)
