Think YOU had a bad day? I got into the office this morning and the first thing to greet me was this e-mail! Yes, I bought that Hoverboard at auction in 1992 for $3k. Yes, I sold that Hoverboard in 2010 to a guy in Finland for $11k, almost quadrupling my investment. Smart move, right? Wrong! 11 years later, that same Hoverboard sells at auction for US$506,000. This is heavy! Great Scott!
