I'm graduating in May, and I want to backpack Europe for at least 2 months before I have to go into the real world. I have a general idea of where I want to go, but I kinda looking to just meander as the wind blows. what are some recommendations for cities/sites that I can't miss. Any places I should try to meet up with friends? About how much should I expect to have to save up? Any tips or tricks of the traveling trade? Any help at all would be greatly appreciated!!!
