But I went to Mount Rainier today - hiked from the parking lot at Sunrise, up to Dege (DAY-gee) Peak, on to Sunrise Point, and back. Round trip: 6 or 7 miles. Which isn't a lot, but it's up and down, and it's up and down from 6000 to 7000 feet or thereabouts. Also, I had my camera, tripod, water, and other stuff jammed into a daypack, which probably didn't help.
So, I'm exhausted in a different way than I was 24 hours ago. Also, I suppose.
Also, I'm dusty and probably smelly.
Good stuff.
