Yes, it is too bad we don't have better connections here. I did mention the possible need to spend the night, though, right?

I'm not sure this part is correct...
> Apart from the shuttle, I could drive from the Bay Area, hit the TH before noon, and camp at about 7200 feet that night.

It would take 4-5 hours from a Bay Area airport to Giant Forest, and with all the logistics involved, it would be a very long day. That night in Visalia (or near the trail head at least) isn't such a bad idea. And with that, you don't have the cost of a rental car parked someplace while you are out on the trail.

The "natural acclimatization" features of the HST are nice. I keep eyeing that trip. ...hoping for next summer, with a climb of Black Kaweah included.
