Nah, gold around the neck and diamond rings scream "Big Hat, No Cattle"dihappy wrote::)
So i gotta ask, whats an "rich looking, older white guy" look like?
Did he have a bunch of gold hanging around his neck, or a rolex and diamond rings on?
Maybe he was in an Armani suit, or holding a bottle of Cristal, LOL.
"Rich Guy" in this sense let's see... well-groomed, nice collard shirt (nice clothes and shoes all around), expensive looking watch (shiny!), expensive pickup truck, etc... Oh yeah, and a GIANT WALLET sticking out of his back pocket. He refuses to use a bi-fold, and now carries a big leather full-bill size wallet that sticks out of the back of his pants 3-4". It has a silver star/emblem on it too, just in case it didn't catch your eye right away.

To be honest, he could be black, white, brown, or yellow and I would still think he had money. Some people just carry themselves that way you know? He strikes me as the kind of guy who walks around with a lot of cash ($300-1000) in his wallet at any given time, and I happen to know that he does. I know that's not "rich", but it's a good target for a typical mugger/robber.
Personally, I prefer the ripped jeans and a T-shirt look with old shoes so the Bad Guys(tm) don't know how much money I've got.
