Get on a random train without knowing where I'm going

is to forget that I got on a train, and be surprised that I am already at my stop, when I thought I still had to transfer trains. I also ran into a garbage bin when I was trying to study and walk to the exit at the same time.

After night with friends, I get on train in my city and not know where it go. It go far, and I forced to sleep in station in cold! Not recommended

Ever since I heard of somebody doing this I have found the idea fascinating. I think the place to do it is Europe, because you can end up in a random country, not just a random neighbourhood of the city you were in (which could well get you killed in some cities).

The reason it attracts me is that it just seems so free, and I love to travel.
