Bummer that timing on your trip didn't coincide with Cannon being in better shape. Hardscrabbles aren't open and many glades still need more snow. Looks like you saw the potential, though.
Cannon's reputation as narrow and old school skiing is really overplayed. As you saw, Cannon has a lot of really wide trails. But there are a lot of windy and somewhat narrow trails (Upper Cannon, Upper Ravine, Vista, Taft, Hardscrabbles, etc. all come to mind).
But the mountain really shines when everything is in play. Much as it is my favorite mountain, I don't ski it nearly as often as I used to and I tend to wait until things fill in. Don't be afraid to do a Mittersill run if it isn't "open". I actually prefer it when it is "closed".
