Scissors,
Have you ever been to DL? Have you ever actually been in the school, and not just at the athletic complex? And I use the term "complex" loosely; if they are recruiting then thay are sure not luring them in by the dozens with their fine facilities. Your comments are typical of someone who has no clue of what he/she is talking about. You think you know, but that's where it gets dangerous.
What the brilliant mind of vandy1 was trying to say was simple: DL's kids are predominantly a product of the Lipscomb community. Most families send their kids to DL because it's where they went, or their family went, or both. The school's been around for well over a century, and is not one of these white-flight, Johnny-come-lately types that is seeking to make an immediate impact on the scene both athletically and academically while also weeding out any undesirables. Some of their kids came after Kindergarten, but that's simply the nature of urban schools, both public and private.
