Remember not to go skinny dipping upstream from the waterfalls, though.
I envy kids who grow up in CA, with their memories of family vacations to Yosemite and all.
BTW Kings Canyon is a great alternative to Yosemite in the summer - it gets busy, but not insanely so, and while it doesn't have the BAM! impact of Yosemite Valley, it's still quite remarkable.
