Looks like the one on Summit Avenue is not up at the moment - perhaps they moved.
Giant Spider has been up all year.
If it's the one I think you mean (near Garfield, as shown on your map) they have had a few of their zombies out since the start of the pandemic, masked up and all. They're still there as of this morning when I walked by.
(OT but on my walks I pass by a lot of things that have made me smile, like the dinosaur with the jokes near Clinton School. I know that's your neighborhood Jamie and if you know the people who keep the "christmas cracker/ third grader" jokes in constant rotation, please tell them thanks from an old woman who loves them!)
The monster tree on the corner of Oakview and Summit is worth a look.
More imaginative/humorous than scary, the Crescent Open Badminton Game (skeletons vs ghosts) midblock South Crescent, which does not appear on the above map, is well worth a look.
363 Beech Spring in SO made the list last year, but not this year. It's certainly worth a look.
