Storm Trooper on a Train

Well... Actually an accordion bus. But I was helping my mom give info on VIA's new Eco friendly accordion buses during a large outdoor health fair, when it started to get hot. (Not unsual. This is Texas, it was 100F at the time, so many people were coming on the bus for air conditioning.) suddenly, some star trooper guys, who were raising money for their Cosplay group. (Which supports a children's hospital, I think) came in to cool off. I got to snap this picture before it got crowded.
