When all I can ski is blue groomers I'll call it a life and move on to fishing and other past times. Might go out once in while with my girls assuming they still will have me but I've got no interest in cruising groomers on regular basis. I guess it depends on what you call "Quitting". I ski ~60-70 days per year and anything less than 10 days would be quitting in my book. It would be like going to the movies or visiting the museum. It would become something you do every now and again instead of a way of life...that's what a I consider quitting. So maybe I should have voted no I'll never quit.
That was a funny stream of consciousness. But I know just what you mean.
I don't know what I'll do, it depends on a lot of things. I agree with UGA that I wouldn't ski as much, but I don't picture quitting completely unless it is wholly necessary.
I have a kind of similar thing with tennis -- I used to play several times a week, but I have a painful foot, and it makes it really tough to play well, consistently. It often ends up being more frustrating than anything. So I haven't played much tennis lately.
It's hard to compare playing an hour or two of tennis with spending a day skiing, though, on so many levels. Especially if it's an indoor tennis court, or it's hot outside. I don't like heat, and the draw of being outdoors is lost on an indoor court. At least with skiing I can still go out in a brisk wind on a mountain ... even if I'm just riding the lift around and around, I think that would make me pretty happy. :-)
