I lived in Denver (Brighton/Boulder/Westminster) for 5 years before moving to CA. I loved it so much I bought a condo there for when I decide to get out of Kalifornia.
The canyon riding above Boulder is awesome.
If you're single I hope you like blondes. 98% of CO women are blonde. I don't know why. Just seems that way to me.
The housing market is prime to buy right now. Values were never too inflated but they have come down and are affordable. Schools are generally very good and the highways are well maintained. The airport is a major haul from anywhere.
The snow is one of the best parts. It comes, you play, it melts. Roads are always cleared the same day.
My advice to new residents: don't drive in the first snowstorm or the last snowstorm.
By the time the last snowstorm comes around, all the people who wrecked in the first one are just getting their cars back
Good luck on your decision
