Thanks Buck and Dave. It really is just the area around the Giants that I'm concerned about. I'm not concerned about the elevations or weather at Yosemite. The elevation of the trailhead to General Sherman is at 7100 feet. I was hopeful that if snow was definite, then I could just ride the shuttle and back track a little. However, the shuttle doesn't start running for the season until 4 days after our visit. If the Mariposa Grove was open, then I would just skip Sequoia and book an extra night at Mariposa, and another day in Yosemite. Since that grove is still closed though, I wanted to go to Sequoia. If they let me in the park, there shouldn't be a problem. If the weather is going to be bad up high, then I don't think they will even let me into the park. I guess we shall see.

Thanks a bunch for the confirmation on the convertible. That makes me feel better. It hasn't stopped raining in DC for almost 3 weeks now, so I'm having a hard time remembering what sunshine is like.
