The National Parks-PBS Video
I urge you to watch it. It is a very nicely made video on the breathtakingly beautiful natural wonders in America. Personally, I found the words of John Muir's in finding his spiritual conviction from nature moving and articulated in a way that I might never be able to. Truly, God expresses himself through the mysteries and beauties of nature. To be blessed to see even a bit of it, is to be humbled by the vastness and bounty of it in comparison to our very, very smallness...
I urge you also to spend time deeply communing with nature. :) The experience is unparalleled in bliss and is true communion with God.
