What used to be a nice, safe neighborhood near uptown no longer is. Leave your car doors unlocked if you park on the street overnight, or else you'll find the windows broken by morning by kids looking for stuff to steal (happened to a coworker, the one night her husband forgot to not lock the doors).
In the last two years, theft of catalytic converters from cars, as well as carjackings, have skyrocketed citywide. It has definitely changed the mood on the streets.
We also have homeless camps, which get cleared out when the annual deep freeze comes through (amazing that people try to sleep outside when the temp can drop to -40). Those same encampents leave used drug needles all over public parks adjacent to schools.
Granted, I'd have the problems we have over what CA cities have to deal with, but then again I also chose to bail entirely to live out in the countryside.
