I was actually in Athens when I read @Liketraveling’s excellent story on having his bags cut open while traveling from Athens's airport recently (just for the record Liketraveling, I didn't do it)! Fortunately, the would be thieves got nothing from him as he was well prepared. On my way back to the airport, taking the very same train he did, I prepared myself to run the gauntlet. Beyond the usual precautions I take while traveling, such as using zippered pockets, and not keeping all my credit cards in one place, I made extra sure I would not be a victim. I succeeded in getting to the airport intact, thanks, perhaps, to Liketraveling's timely warning.
