Skiing: Putting a camera on a tripod, unattended, on the piste? Then get the lift up to the top so you can ski back down towards the camera? Again, I can't see this ending well for the poor old camera.
On the other hand, this represents a great business opportunity for ski resorts. The ski resort has a few soloshots mounted near the snowboarding rail park, and $5 lets you wear a tracking armband for 5 minutes. Drop it in the bucket at the end of your run, get an ID number which will allow you to download your footage at the end of the day.
In fact, if a ski resort wanted throw a ton of money at this problem, they could put soloshots along the entire mountain, and you rent an armband for an entire run down the mountain. That would however require sophisticated software on their end to collate all of the camera feeds and stitch together a single video file of your run down the mountain.
