Brown weekend....that's just wrong.
We always call what you're calling "brown weekends" "black weekends". Did you have something else you called a "black weekend"?
Nothing takes the shine off a "golden weekend" like the guy who reminds you that 'normal' people just call those "weekends"
At my program you do two brown weekends a month, which sucks, but the advantage is you then get two golden weekends a month as well.
It seems like the work-hour rules has moved the US over to pretty much 100% silver weekends. I'd personally rather have 2 browns for 2 goldens.
