Correction & advice from a reader: “Extremely nice pictures from

Yosemite — a wonderful place for a family vacation (I remember my trips as

a child very fondly, and my wife and I will take our children there as

well). Just as a nitpick, however, Tenaya Lake (approximately 9,000 ft.)

and Glacier Point (approximately 8,000 feet) are both substantially above

the top of Nevada Falls (approximately 6,000 feet). Some day when your

children are a mite older (while you and your wife won’t have aged a day, of

course), the hike all the way to half dome might be worth it — truly

spectacular views, and teenagers who have done it feel proud.”

I appreciate the correction, Sir. Roger on your last, too: I remember the

pride I felt after hiking up my first mountain.
