Hi Ang,
I moved to Denver nearly 4 years ago. I currently live in Lakewood, but I did live at the border of Golden.
Cost of living is significantly lower here in Denver. You'll see it in gas prices. For instance I pay $2.28 for gas.
It's a family friendly city, but it can't beat the 70 degree weather year round and the beach. Don't get me wrong, I'm blessed to live in Denver. I'm glad I'm not under the reign of the Terminator anymore. pm me if you have any more specific questions.
I'll tell you though, Golden is a nice small historic town if you like that kind of thing.
