Bay View does a lot of Halloween decorations in October, but hands down the best display every year is Zombie Hill on Kinnickinnic near my kids' school. (And I never get tired of the word "Kinnickinnic.")
How awesome is that? The first few zombies appear on the
hill on the first of the month, then more, and sometimes they get moved
around (usually closer and closer to the sidewalk as the month
progresses).
