I celebrated my 13th birthday at Yosemite with my family. We also visited the giant Sequoias on a car trip when I was about six. Unfortunately that's the extent of MY experiences with the listed places. I might have marveled at the night sky when I was at summer camp as a teenager, but nowadays, thanks to a lot of light pollution where I live, I don't see anything in the night sky other than the moon when it's bright.
