Navigation Menu Bar Issue

On my site http://www.txcleanenergypark.com
on the menu navigation bar “sustainable communities” is now on the 2nd line underneath everything else. Is there anyway I can allow for more room on the menu bar so additional menus are not squeezed under to the second line?

Thanks

Add this to Theme Options - Other - Custom CSS

#main-nav a {
    padding: 8px 6px 0 6px;
}

Of course menu items will be now squeezed together but there is no other way around it uneless you make them shorter.
