Win a place among the worlds' first commerical time travlers, the email said, busted words and all. No entry fee!
The mail had been routed to my spam folder; there was no way it was anything other than a half-pound of horseshit. But I was tripping balls, and this was the funniest thing I'd seen in a month. I gave them a throwaway email address as a goof.
Even the followup mail that came to the throwaway a couple of weeks later, that was just a goof too. You know how it goes. I gave bullshit "information", didn't give my bank accounts or anything identifiable (I'm not stupid)... but I wanted to play them for everything I could, you know? Maybe I'd get a good /r/spammerbait out of it.
So we went back and forth for a while, and I was getting all sorts of funny stuff. Just a goof.
Until the guy in the suit shows up at my house.
