Thanks for the great suggestions.
We should do another trip to Colorado (we did a great road trip there a few years ago). I've never been to Glacier NP, or more northern Cali, so Shasta sounds good too. We've been to Zion (but didn't do the narrows), I'm planning Cloud's Rest for my next trip to the area, perhaps in a year. I've been up El Cap (not the face, but the E. Buttress).
This should be enough to get me started! K
