I know it can get hot in Denver and other parts of Colorado in the summer, but the weather year round is still generally more to my liking than it is in NJ. Weather is not the only reason why I want to move there one day though, I love the state for several reasons.
Also, what I meant by "extra traffic" is that I live in Southern NJ near many beaches, so the area gets significantly more congested with people from the Northern NJ, New York, etc. driving down here in the summer for vacation and to their beach houses. It's just one more reason why I never look forward to the summer down here. I really enjoy winter and fall down here though because it's a lot quieter, so if I do eventually move from here one day I'm sure I'll miss that.
