Wow you guys, and you say that women are the crazy ones. 22 years and you're obsessing that your ex-wife is coming into a town of 3m people plus just to find you? Are you kidding me? Despite all of us complaining about the prices here, BA is a hot ticket. When I was home in Vancouver I was walking down the street and heard some water delivery guy talking to a man with a dog who had run up to him and turned out both the dude earning minimum wage (approx) and the old guy had been to BA within the past 6 mos, and then some other woman overheard them and piped up oh I was just there last year, yes my daughter lives in Reeecoleta, I said nothing but continued on my way to the coffee shop where I met up with a friend who of course wanted my opinion on his upcoming trip to guess where, B-effing-A. So I doubt your ex of 22 years past is tracking you down, it just happens this is a popular place to visit.
