Dear A.,
I am originally from Washington state on a rural island and lived in Alton Il while going to college. I am now currently living in Burbank which neighbors Glendale. Just like any city there are portions of Glendale that are very nice and are safe - stay away from the southern end! I am right at the border between the two cities, east of the 5 and feel quite safe here. We go for walks (my two year old and I) in the evening almost everynight after dinner and I never worry about our safety. However, I also recently did an easter egg hunt with her that was a mommy and me and was incredibly disappointed by the behavior of many of the adults who grabbed eggs faster than most of the kids could walk (granted it was on behalf of their kids but it took the fun out of having to find the eggs. My daughter was able to grab one but there were many children there who didn't even get one egg because the parents were trying to help but not "do for". Having grown up rurrally this was not my expectation - my husband who is from here says its just part of being in a ciity - I guess we'll just do our own hunts from now on.
As far as schools go, I can't really tell you yet - we aren't at that point, and we are with Kaiser so I can't suggest doctors etc. unless that is the health insurance you will be having too. My husband, who is a realtor, says the Burbank schools are some of the highest ranked in the state and I know the highschool is considered a "distinguished school", an awarded title. There is quite a community of deaf people here so they have a GREAT sign language program and having access to that has been wonderful for doing sign with my little one. The neighbors directly around me are pretty friendly neighborly people with only one exception and a few people who just kind of keep to themselves (which is obviously fine). But it is the first community I've been in in SoCal where people are neighborly and don't just keep to themselves all the time.
I guess I feel its a mixed bag just like anywhere else you might live. I would suggest Burbank over Glendale though, or at least the area of Glendale nearest Burbank. It is a little cleaner looking here, more trees, etc.
R.
