What company in Boulder? I work in Boulder.
Colorado is the best place to live by far!
The cost of living is comparible to Raleigh.
Fort Collins was recently ranked #2 as the best place to raise a family in the US.
The winters are not really that bad. There are a few days where it gets really cold, but the sun is almost always shining and it warms things up a little.
If you like the outdoors, Colorado is great! There are some very good B&Ms out here too!
