This is just a preference of mine, but I really don't like it when there are two lines in the navigation bar. I figure it should be one line, with perhaps another custom menu in the side bar if you needed it..
Another solution would be to re-think your navigation. Have an About Us item with a drop down menu including site map, sponsors, Facebook Feed and Privacy. That would bring it back to one line
p.s. Did you check your Facebook Feed page? It blows out the side of your template. Can you not set the width?
