I'm leaving CO because the air quality is so bad out here, especially in Denver. Sixth worst last time I looked.
Denver has a vibrant tech scene like Boulder and you will find they only ask for normal work hours. Work life balance is a big part of the Denver culture. People love the outdoors activities, sporting events, and drinking. This is a heavy drinking / drugging town (another reason to leave)
If Denver sounds like your preference, I can tell you more about the neighborhoods and put you in touch with an amazing apartment search company. Literally the best experience I had looking for a new flat, they did everything, scheduling viewings, Uber you around, buy lunch.
Austin is another great consideration. They don't have state income tax either.
I actually ended up choosing Seattle, it seems like more my vibes (being less laid back for one), I already got a college buddy there, the housing prices are similar, and it's more walkable (don't need a car!).
I'll be reevaluating after a year and maybe hop down to Denver (Seems like it would be great place to combat the 'Seattle freeze' if that's really a thing)
