There is no age, height, or weight requirement to skate. It is good exercise no matter what your age is. If you want to be competitive, most start young. But, I practice with many adult competitors.
The fishing is a great relief for me. When I'm out there's no cell phone ringing. I'm out there fishing with bears. I'm in the middle of God's country catching tons of fish. I just absolutely love it.
What makes me different from everybody else just boils down to dissatisfaction.
