Well the discovery channel had something about the super volcano aspect awhile back......
I used that as reason not to permanently move to Wyoming....
So yellowstone blows, polar ice caps melt, 2012 happens, polar shifts etc.......and then the asteroid slams into earth and the Aliens return!
Lions, tigers and bears .....OH MY!
Seeing how I am not pretty locked into my location ........I figure I am screwed, just let me know when to kiss hubby and kids goodbye!
