If you do White, don't underestimate the rather long time it takes to drive to the trailhead. The road after the Shulmann VC can be rough, and often the rock is very sharp.
On Sunday, September 5, there's "Open Gate" day at the trailhead, so you can drive up to the Barcroft Station, and save about a mile of road walk and 1K'+/- of elevation gain. You also don't have to worry about the marmots chewing on your tires if you park at the station, either.
