My first backpacking trip was around 7 Lakes Basin in Olympic National Park. I was thoroughly overpacked and undertrained for it, but still had a blast! The views are, to this day, the best I've ever experienced on a trail.
I was so afraid to dig a hole and squat for my.. needs.. that I held it in for HOURS while practically sprinting towards the next camp area. I was miserable during those hours, but still an incredible trip!
