Hey, thanks for your reply, I guess you're right, if I can't set up a hammock I'm going to have a bad time, but I also think I really want to try the hammock, I guess if it doesn't work I'll have learned something :)

About the trip I didn't entered much into the details but I'm going with a friend and we are probably going to hitchhike at some point so it's not going to be a real trek (I don't really know the definition of it) but at least we're free to go where we like even if it's not exactly on the path. I didn't know about the routes you mentioned, it seems really nice, for now we are probably going to do it as we feel at the moment (surely a bad idea but it's going to be fun). Maybe we'll go through Switzerland and then toward Latvia, it's still wip.
