Welcome aboard. You are right; a lot of good players from that area. See, you just gave yourself a job =).
As you can probably imagine, a lot of the commenters here are related in some way to the kids they are talking about (though there also appears to be a fairly sophisticated "scouting" community). Folks see something and want to share; most of the information is pretty good, though you can probably figure out soon enough which of the commenters are just grinding an axe or simply trying to get a certain kid's name out there. Also, there is a good Virginia Preps site that has info (though I think most would say that it is more public relationsy) that publicizes high school sports.
I am certain that there is a lot of good information as to prospects and the happenings in your area. You should start a thread of your own. Again, welcome aboard.
