Do it.

1. More trout for the rest of us remaining in Colorado *S*
2. There is a higher proportion of scantily clad potential significant others in Florida. Well, unless you lived in Boulder, maybe.
3. It doesn't snow in Florida, nor does it get to -15 like it does in Denver.

Seriously, though, if your work is where you are, then there is no reason to not BE where you enjoy life the most. You work to live, not the other way around. Or at least that is the way I think it should be.
