Guess where I visited while we were in Hawaii for the past 2 weeks?

Saw all the scopes, got to go into the Keck and view the mirror from inside, watched the sunset at 13,700+ft while enduring less than 4 degrees Celcius and 55mph winds, then settled back down at 9000ft for a little stargazing from 6:30pm onwards. They setup a few scopes and pointed them to different objects: Mars, Andromeda, Pleides, etc... Then had a little talk about different objects in the sky. Twas awesomo!
