I am converting a site from D6 to D7 and am having a problem with nice_menus. There is a white line above the menu items and I can't figure out how to get rid of it.

My site is at: http://dev.earthednet.org/

It's still ugly, as I'm just theming it now. One by one, I am solving problems, but the line above the main menu drop downs has me stumped. 

Any help would be much appreciated.
