How old are your kids?
Are you using a realtor to help you find a place to live (buy or rent)?
I have found, having moved many times in my adult life that the following helps" 1) Be as extroverted as you can tolerate. Say hi to other parents at the park, grocery store, the kid's school, etc. 2) if you work w/ a realtor describe to them what sort of neighborhood you want - what features, community type, etc. A realtor who has worked in the area for sometime will know how to help you find this stuff. 3) talk to your new neighbors, look for local mom/parent listserve, sign up for classes or kids' activities.
I lived in Hollywood, FL - but almost 20 years ago and as a single grad student - so my information is many years and 5 cross-country moves out of date.
