This is correct and meets the OP requirements. Well under one hour to a major int'l airport hub, 30 mins to South Denver Tech Center, less than that to downtown. Light rail is expanding to DIA, and if you can't beat the traffic rush up in the morning from west side locations you should re-evaluate your priorities. I live 30 mins south of Denver and an hour from the western communities, have four kids and I spend little time in ski traffic, although about half my days are weekdays and I am not skiing Summit County on the weekends. We have excellent schools in many places without a huge housing cost premium.
It was stated earlier that Denver has terrible air quality - it is much better than it used to be and where I live air pollution is non-existent. We have major cultural amenities and excellent and diverse higher education across the region, along with a population that is becoming increasingly 'progressive libertarian' rather than stuck in any one ideological rut.
It is, for all the pros and cons, a region where you can raise kids and they probably won't be looking to get the hell out. Smaller, more provincial places can be bucolic for adults and boring prisons for younger people. The inner city of Denver itself has been revitalizing and growing for a couple of decades and the mantle of 'Manver' has been passed elsewhere. Second homes in the High Country aren't cheap, but a condo or duplex is well within reach at reasonable income levels. If you hate cities, and hate them more as they grow, then obviously this is largely moot.
Now, this is just one way of looking at things. SLC to me is a lateral move (not many people are likely leaving one for the other, hence the endless debating).
I'd want to get someplace like Vancouver if leaving here, gaining coastal access, and that is a whole different cost of living model.
