PBG also has festivals and whatnot, right now the Greenmarket is in season on Sundays. There are a ton of other parks and playgrounds scattered around, some w/ 'big kid' things such as tennis courts, basketball courts, jogging tracks, heart trails, etc.
The Gardens Mall is wonderful and very high class.
Lots of other shopping as well, pretty much anything you can want is within a 5 minute drive. My husband teases and says I live in a box because I don't have to go more than a 5 mile radius of our house.
PBG is also very close to Jupiter and Juno Beach, which are wonderful towns as well. Beaches are gorgeous, and well kept. Abacoa, in Jupiter, also has a ton of stuff going on.
Not too far from CityPlace in West Palm Beach for nightlife.
I highly recommend it. I have lived in Tampa, and moved back to PBG a little over a year ago. There is nothing quite like good 'ol PBG. But if you are looking in the area, Jupiter, Juno, Tequesta, North Palm, and PBG are all good areas.
