Most memorable outdoor experience

I'm kind of an astronomy geek so my best friends and I all went backpacking through the Shawnee National Forest in Southern Illinois this summer for the largest meteor shower of the year.  We hiked to the top of one of the bluffs for an unforgettable view of the most perfect sky I'd ever seen, with more stars than I even knew existed, and at least two to three meteors a minute.  It really was unbelievable.
