I was just in a sort-of similar situation a couple of years ago - 23, just finished my Master's, starting my Ph.D., just married, and moved across the country to Pittsburgh.
It was actually a lot of fun, until my wife got pregnant and we had our son. Now virtually every post-doc fellowship I'm currently applying to is closer to home. For the sake of my kids, I really don't like having them this far away from their grandparents and other family. Thus, don't have kids until you're ready to head back home! lol
