Is it selfish for me to want to take this job opportunity?

I've got a chance to work in Denver for a year, which is really exciting for me since I've always dreamed of living there, especially because I love cycling and the great outdoors. Our little one would be about a year old by the time we'd move. My wife, though, isn't thrilled. She moved a lot as a kid and now, more than anything, wants to put down roots. She feels moving around isn't good for us as a family, especially with our track record of not staying in one place for too long. I see this as a once-in-a-lifetime adventure, but she sees it as me not considering what she and our family really need.
