Yes I got seriously caught out with this - the phatness post is really helpful - but it's a pity there aren't warnings / directions around this in the BS sample content. I tend to class styleable outer divs enclosing the rows as ".enclosure, given ".wrapper" might be confused with historically similarly classed divs which are actually equivalent to the outer .container element in BS
You're almost worse off if you are experienced with other frameworks, such as 960.gs, where you can style rows with total abandon.
