It will be interesting to see how they build the balloon track at the Summit. It's been a few years since I was there, and when I was there, the place was under 15 feet of snow. That said, I don't recall there being much room for a balloon track right there at White Pass Summit. I recall there being a lake on the west side and a pretty steep slope on the east side. Not much in the way of flat land except for the main line and the big passing siding there.
