I'm in the same place as you, only about 5 years older (meaning I'll be too old to hunt 5 years sooner than you ). I've been looking over the numbers, and there is simply no way to make it look pretty. The thing that bothers me most is the tidal wave of point holders in the 10-12 point range. When those point classes start drawing, it's going to drive some crazy point creep. It's all an unknown, but some unknowns look worse than others.
15 years I can manage. 20 years would still be worth it. 30+ years? Crazy. If nothing else, something will change in the draw system, and who knows what all those points will be worth?
On the other hand, you can't win if you don't play the game.
