I picked "other". "Other" is caving, climbing, hiking, mountaineering, canyoneering, rafting, canoeing. I have participated in all these outdoor and adventure sports. I enjoy watching them as well as the winter olympics.
I put my vote in for 'Xtreme Games', but just for future reference, those of us in the field would rather use the term 'Free Sports' if we have to be lumped into one big pot.
