Yeah, i ain't no zipper bump guy, never was. And I ski the Jane a usual 30-40 times a season. But not much on the bigger bump fields.
I liked Mary Jane best, however, when it was powder glade skiing, when one would traverse over to hit it, and then traverse back at the end. (In other words, when it was an outside of the resort traverse through the woods, long ago - no lifts there.)
At one time, later, the U.S. bump team would be based there, and would train as a group on the Mary Jane bump runs. I'd sometimes tag along, watch them do their near super human thing from above, so amazing, then ski over to an easier run myself.
I tagged along because a friend and regular ski buddy was on the team. He ended up an alternate for their Olympic team twice, both times just one place away from going to the Olympics. But he never made it.
One evening over a beer I told him I had decided to get more serious about trying to do bumps on the zipper line, like he did. A New Year's resolution, maybe.
To my surprise, he advised me not to. He said he'd had five knee operations on each knee, and after his competitive days were done, he would probably have to give up skiing entirely, just to stay able to walk and run. He was thinking of opening a scuba shop in Florida instead, in a situation where weightless walking prevailed underwater.
He actually became a manager of a scuba shop in Key Largo, and has not skied in years.
