If a one-wheeled century (see blog of 05/07/2016) is amazing, a unicycle tour thousands of feet up is even more astonishing. Thinking of just being at that altitude makes me feel like I'm gasping for breath; never mind strenuous physical activity there.
Leaving altitude problems aside, it sounds like a wonderful adventure. The photos accompanying the article are gorgeous. I've always loved mountains, perhaps because I've always lived where it's pancake-flat. And at sea level, too. No wonder the thought of locales a mile or more "up there" make me breathless!
