I think I'll take the Keck Observatory on Hawaii's Big Island, thankyouverymuch! I spent six months there for HIRES (HIgh Resolution Echelle Spectrometer) first light.

If it is naming rights, then I would love to have the naming rights for the new Lucas Oil Stadium. Only I wouldn't rename it for myself. I would call it something like "The Citizens of Indianapolis were conned into financing this stadium". or "Jim Irsay is a spoiled brat Stadium".

My first idea is an animal shelter.

My personal dream (If I won the lottery) - is to build a ranch for feral cats, staffed by vets and animal lovers, where each cat had its own little victorian cat house. It would be open for people to visit, and ideally adopt the cats.

If, when I die, the funds are there, I would love to finance a private room in my hospital's ER for at-risk patients (ex. chronically ill presenting with an acute situation).
