menu width

fixed! don’t know if its the best way, but this is what I did

.row-fluid .span9 {
    width: 95%;
}
.navbar-inner {
    margin-left: 0 !important;
    margin-right: 0 !important;
    padding-left: 0 !important;
    padding-right: 0 !important;
}

.nav {
    background: none repeat scroll 0 0 transparent;
    float: none !important;
    margin: 0 auto !important;
    padding: 0;
    width: 85%;
}

still trying to get the menu to align to the left though

#access ul {
 display: table;
 margin: 0 auto;
 width: auto;
}

the above css gave the menu perfect alignment and made it fit into one line on widescreens.
