Try the Baltimore Area Officials group and Lee Carter. He has a lot of info on his site for the greater Baltimore area and camp info as well.

For high school ball you need to figure out which board will best serve you but the infomation is at mpssaa.org
If you are interested in trying out for the Capital Conference (D3) send me a PM with your email address and I can forward the camp application to you.
