Colorado is culturally much more in tune with work-life balance. Especially in Denver imo. No one brags about working 80 hours a week as that makes you sound like a loser who doesn't ski/hike/bike enough.
Same here in Portland. The companies I've been involved with here tend to take pride in their employees being active. I could see this changing as the Valley types continue to move in, however.
In 12 years I don't recall any jobs with fewer than 15 days. My current job is "unlimited", and I took nearly 25 days one year.
