I'm not sure if I'd go that far. It's incredibly dangerous, loud, and you end up covered in train dirt, which is a special kind of black greasy dust that gets inside your ears, nose, everything.
That being said. I have never felt more free in my life. I traveled 700 miles for free and it was completely illegal.
Many more details to share; such as the different train cars and two attempts to board a moving freight (one successful, one unsuccessful).
I'd be down to do a podcast rip about it, but typing it all out would take me over an hour.
