Last week I took my 10yr old son  for an adventure up to the top of Mauna Kea and it sure was beautiful. As far as the eye could see were clouds and blue sky , only the peak of the other volcano could be seen on the horizon in the distance. It was so very cold at the summit and apparantly the temperature dropped to about freezing by night time. I felt a bit sick from elevation sickness when we ascended to the top and with only astronomy research centers in egg shaped domes and black rocks, it looked like what I imagine a journey on the moon would be like. Apparantly the astronoughts did practise on top of this very mountain to practise for their journey to the moon!
