About myself and the trip:
- I am a 6'1" (185 cm), 23 year old American male traveling with another 23 year old male friend.
- I arrive in Barcelona in June and leave from Copenhagen in July. In between we are visiting France, Italy, Switzerland, the Rhine Valley, Belgium, and the Netherlands.
- I am planning to stay in hostels pretty much every night.
- I don't intend to get any souvenirs.
I need to buy my backpack soon, but don't know how large of one to get. Any advice would be appreciated. Please let me know if there is any other information I can provide.
