I live in Denver. Why?
Snow capped mountains, nice people, and it's far more liberal and open minded than you can imagine.
Oh yeah... where else in America is pot legal? Yeah, but who wants to live in Washington? :-)
Gentoo and openSUSE are my distros of choice.
Why Gentoo? Power, Freedom, Flexibility, Security.
Why openSUSE? Professional design, stability, ease of use. Yast, kiwi, and SuseStudio rock!
