Setting up the Logic on a Custom View Sort

Setting up the Logic on a Custom View Sort

Hi Guys - I am trying to create a custom view excluding certain states so I pull up everything but what's in the MD, DC, and VA region. Each time I've tried to do this, it hasn't worked.  Does anyone have an idea on how to set up the sort logic so I don't have to include every state, but just exclude the MD, DC, and VA states?  Thanks.
