I found some great posts on centering the menu for the TwentyEleven theme's menu, but I need it to go one step further.
I've created a child theme and followed the code advice from this post: http://wordpress.org/support/topic/how-do-i-center-the-navigation-barmenu-on-the-twenty-eleven-theme?replies=9
However, the menu I'm working with has more items than will fit on one line. So when the menu rolls over to a second line, the second line is not centered. It starts from the left side. Here is the website I'm working with: http://cap.tombird.com/
Any suggestions? Thanks in advance.
