Gary: You are such a great help. We'll skip Mt Whitney. There are flights into Visalia. But I'm not sure about the rental car situation.
Renting a car in Monterey and returning it in Visalia...I know it costs more and hopefully these towns have such a thing (we did this in Fairbanks to Anchorage- but they were big cities)
So, would the end of May or Sept be better as far as the waterfalls?
If we only went to one place of the following which would you recommend: Yosemite or Sequoia/Kings?
