1) Go to Chernobyl and see the sarcophagus.
2) Write a (good) book.
3) Get the book published.
4) See the Northern Lights in the Artic Circle (as opposed to a dim-but-dazzling display over Ireland).
EDIT:
1b) Radiation and security permitting, climb to the top of Reactor No. 3 and 4's cooling tower, and take in the view.
