I recall we had this same thread last year, or was it 2 years ago. I highly recommend my old neighborhood, aka Northwood/Northridge [Think inside Harry Wurzbach, Eisenhauer, Nacodoches and Loop 410]. I'm not saying it's the best, but it is/was pretty lively. Lots of trick or treaters go out of their way to to get there.
That was 4 years ago. Things may have changed.
