I also attended an interesting session by the National Parks Service on conserving dark skies and how EPO can be done through the NPS. Now I want to be a park ranger. I'm seriously considering moving to Yosemite.
To round off the #nerdweek day 1 I got to listen to John Grunsfeld talk about the STS 125 mission. Very inspiring - now I want to be an astronaut too :)
