Frank - I had trouble getting my pics and commentary into this Post format, so lots of info left out.
We did a straight shot from Roads End to Bishop Pass TH at South Lake. My wife dropped us off and picked us up (what a gal!). Skurka gives some insight for do it yourself, one way trips.
During our timeframe, Aug 1-6, the only pass with any real snow was Frozen Lake Pass on the east face, and conditions were perfect for glissading, even at 11:00 am.
Total mileage was about 58. We were walking 8-10 hours daily - averaged 1mi/hr. The hike was as challenging as everything I read about it. My sons really wanted to get to Bishop by early afternoon on day 6, so we felt some time pressure everyday.
Route was straight out of Roper's book, and Skurka's maps. Once again, when Roper says "stay to the far left..." you can be assured that is the most pleasant route. And there is no reason to add any additional challenges to this route, unless that's your thing.
