In reply to 1poundSOCKS:
> I usually like to keep my options open, which isn't the cheapest way I know. I tend to travel on my own too, which also makes it more expensive. Latest plan is Lake Tahoe in September, Yosemite in October. I think for Lake Tahoe, a car is essential, I could probably do without for Yosemite, but it is always nice to have one, and I am tempted to spend some time in Red Rocks too.
If you drive from Yosemite to Redrocks you could spend some time in Bishop before driving through Death valley and over to Vegas.
