We just returned from a week in Jackson and got to see the tram progress in person. And although you could still ski the same lines without the tram, it was just not quite the same experience.
Jackson is an incredible place in the winter, but is just beautiful this time of year. The temperature is perfect, the valley is still lush, and the peaks are still snow covered. The hiking was amazing, and the white water rafting on the Snake river was awesome. With all the snow melt, the river is flowing strong (and cold!!).
Can't wait to visit this winter.
