I'm pretty sure you rock pretty hard, yourself:)
I looked up Mt Sentinel in Missoula, and imagined the view you must have had. Sounds wonderful, sort of stranded amongst the clouds.
You know what, I hope very much that you're right and I can keep on with hikes now and then - though I think I'll take some easier/shorter ones for a bit. I love the mountains so much, too, and even moreso since I've gotten older (there is NOTHING like a refreshing cool wind for a woman with hot flashes;)
