I have been watching a show on National Geographic entitled, “Into the Lost Crystal Caves,” and I am blown away by it.  I just love the fact that we think we know so much about this planet and others but constantly discover that we know next to nothing.

These caves are amazing!  We are talking thousands of feet deep in the deserts of Mexico, hellish heat and humidity in what has to be one of the most inhospitably areas of the planet – giant crystals unlike anything seen anywhere else.

If you get a chance, watch the two-hour special. I find stuff like this amazing and inspiring.
