You guys are talking about the "Shrine" I've seen lots of cool things in there, including a journal that lots of folks wrote in. It's kind of cool to see where people you know wrote poetry, put down funny things or just told about their trip. I'll usually leave a can of beer there for someone that comes along later, I've seen lots of fun and profound things in it.
Nothing in the world is more yielding and gentle than water. Yet it has no equal for conquering the resistant and tough. The flexible can overcome the unbending; the soft can overcome the hard. - Lao Tse
