yeah, it's definetely not a thing to trifle with. once i was stranded on Crimea peninsula alone and with but a few coins in a pocket. it took me three day to get back home but it was hell of an adventure. i advice you not to do that, because being a hobo in an unfamiliar city is quite dangerous (and if you're gonna stay in your home city then it's not really hardcore). if your mind is firmly set on it, don't forget to bring these things along: asswipe, documents, flask for water, lighter, iron mug, swiss knife, spoon, pen and paper. if i had those with me then (especially asswipe) my journey home would me much easier.
