Everyone has a price.

Rusty's appears to be $500.00.  I'm a little confused as to how Mr. Goldshirt happened to just drive up to the barn where Rusty is presumably taking his pictures without Mark, Cherry, or Doc seeing him.  (Where is Doc anyway?  First they don't take him to the diner, and now he seems to have disappeared from the strip entirely.  That's family for you.)  Apparently, once you've talked to a random stranger at a diner without finding out his name, where he's from, or what he's doing in town, it's okay to talk to them even when you're not with your parents.  (Yeah, that's not good.  Stranger danger!  Stranger danger!  Run, Rusty, run!  Where's that spotted dog to protect you when you need him?)  If you're going to accept the guy's money, Rusty, I'd make sure that those bills are real.  (I'd also make sure that the cops aren't looking for the serial numbers, but that's just a guess as to why Mr. Goldshirt and the longshoreman are on the run.)  Of course, the real question is, if he does end up selling the guy his camera, what's going to happen when the two criminals find out that the memory card they want isn't in the camera anymore?  I sure hope that the Jack Elrod Ball and the spotted dog are going for help because Rusty's going to need it.
