I know how you feel Nick.
I live here in Sydney Australia but im moving over that way in a month, and I can't wait to be able to go to more Bills games each year. I have gone to at least 1 game the last few seasons but as you can imagine Sydney to Buffalo is about 30 hours of travel so it's harder to go to more then that.
I will be going to the home opener and will be living in Buffalo for a few weeks after that before moving down to NYC.
I looked into getting season tickets also and decided as I couldn't guarantee that I could go to most of the games I will get tickets off ticket exchange. Seems like a good option! maybe next year I will get season tickets.
Enjoy being closer to the bills, I know I will!!
