For me it would be sacramento/california. Having spent a couple of months in san fransisco working I can say I love the city but I'd hate to live there, staying there for that long helped me realise that I'd much prefer to live outside of a big city.
If you're looking for snowboarding or something there is bear mountain in california, it's closer to los angeles (9 hour drive from sacramento) but you could probably get flights to l.a. and then get to bear rmountain from there
Yeah - part of me would like to live in a big city as I like the amenities... but I've already discovered that I prefer the space

Good to know about bear mountain, so I can always get my fix without having to trek over to CO... although, I'm not the most adept of boarders

Absolutely beyond jealous. I would LOVE this sort of opportunity. Congratulations
I've never been to the states, but from what I've read, I'd be going for Cali, with Florida a close second. However, don't taxes vary state to state. Where would be the most 'efficient' place to live? I'd let this influence me if there is a huge difference Florida to Cali.
Baring in my that the OP has said he would be a homeworker, and parts of Oregon look like this http://cache2.artprintimages.com/lrg/20/2097/8EP2D00Z.jpg ... I wouldn't discount it immediately. Totally down to what the OP wants.
Thanks, it's something I've been dreaming of since my first trip as a kid
Just had no idea it could happen quite so soon and in such a way 
Yes the taxes do vary, if I take my projected salary as $102k (range is 102-110)... then it's just under $300/month more expensive tax wise in Cali compared to Colorado.
Looks like Oregon is more expensive than Cali (slightly).
Then Florida is somewhere between CA and CO.
CO is also about $0.30/gallon cheaper for fuel.
It would appear CO is the cheapest place to live from my list.
The difference would be $3.5k/year on income tax alone, maybe up to $4-5k/year with the reduction in other taxes.
But then I've also been looking at properties in Sac... seems you can get something gorgeous on a lake for $1500-2000/month in a decent area (rental). That seems to usually include all bills + taxes with the exception of electricity.
)... so while over there I'll try and travel to these places as much as I can.
