Ahh Fremont Street...A nice little slice of Reno in Vegas.  All the casinos were build well before they developed modern ventilation systems, so all the casinos reek of smoke, old carpet, and pee.  More than its fair share of shady characters.  Worst of all, the garages charge parking....Validation is easy, but doesn't make much sense when you can park free at the Wynn but have to pay to play at Binion's.  Go if you must, but keep your expectations low...
