There isn't anything to add to the great answers already priovided by some of my friends. And I have friends who are happy living in all of these communities. We moved here 15 years ago from Herndon. I hope you'll enjoy it as much as we do.
These are all nice neighborhoods. One thing to know about Lake Park is that although it's residents have an Indian Trail zip code, Lake Park is an incorporated town with a number of distinct neighborhoods and a town center. The others are specific neighborhoods.
Please visit http://www.CarolinaSmallTownLiving.com to learn more about Lake Park and Indian Trail. My blog at http://www.CarolinasRealEstateTalk.Info also has a lot of information about specific neighborhoods within Indian Trail.
Let me know if you would like additional assistance in your neighborhood/home search.
