My 2 cents, but I don't understand people feeling compelled to toke up when they go somewhere breathtaking. Is the place not enough? Alcohol is my own motor inhibitor of choice, but I generally prefer to be on my game when I'm out enjoying a beautiful place and save the brew for the parking lot. I enjoy the place that much more sober.
As for my power place, don't know that I have one in particular. I've seen lots of amazing places, and I think the thing that inspires me most is standing somewhere I know has been tread by only a select few. Being surrounded by concrete and asphalt the majority of the time, getting a very real sense for how alive a place can be despite us rather than because of us is very compelling. I need to be reminded now and again that I'm a guest in very remarkable place, rather than a resident.
