CSS/Tables margin/padding issue

[jamieboulder]

Attached is a screenshot of my present header. I've spent the entire day trying to track down this:

The header div ids run like this: navMainWrapper, then directly under that is logoWrapper. Between navMainWrapper and logoWrapper there is a white line app. 10 pixels high which I cannot locate and make go away. I mean all day.

It must be padding or a margin of something, or I don't know what. Big cigar to the dude who locates that issue so I can make it go away. This seems a lot harder than it should be.... site is here; http://oshoboulder.org
