Too many people and places to list! Oh, the possibilities! I'd love to travel to the future to see when faster-than-light travel has been invented, visit colonies on other planets perhaps, go back and see what various countries of my ancestors were like hundreds of years ago - including this one, just so much I'd like to do! And save the dod from extinction, and keep the kakapo and other on-the-brink species from becoming so critically endangered, and that's not even world-changing events like preventing Franz-Joseph from backing down that alleyway ... etc., etc.
