Green Bay Packers season tickets have been sold out since 1960. In 1997 I signed up on the waiting list for Packers season tickets. At that time, which was prior to the Lambeau Field renovation, the estimate was that I would be 51 by the time season tickets were available. Given that there are more seats and the season ticket transfer rules have tightened up a bit, it might be more like 45 now (I can’t find the wait calculator anymore).
While I’m not planning on moving back to Wisconsin anytime soon, by the time I’m that age, you never know. If the packers were having a good season, I would even consider flying back for some games!
