Our neighborhood went up in the 1920's through the 50's, depending on which block you're on (Ours was one of the earlier ones). The nice thing about the neighborhood is that everyone takes pride in their homes. Lawns are kept neat, shrubs are trimmed, and any necessary paintwork on the houses themselves is seen to right away. When agarage in the alley beside our house was hit by a graffito a couple of years ago, another neighbor was out there with a scrub brush trying to remove the paint before the owner even knew about the damage. Even without any formal neighborhood watch, we watch out for each other like good neighbors should.
We do have our share of, um, "Unusual" cars in the area. I have to remember to take some happy snaps of the late-model burgundy long-body Chevy wndow van a few blocks away that's stylin 24" rims and limo-tint windows... but looks completely stock otherwise. There used to be a very rare Plymouth Horizon TC3-based Scamp pickup nearby too.
