If I were going to be a scammer, I would sell the "service" of delivering local results for all the cities in a particular region, such as a state, aka optimizing for "Montana Fudgepackers" would deliver local results in all the local searches for the entire state. Since so many people so fervently hope and believe that this is possible, they are RIPE for the plucking, fat clucking chickens, all it would take is for some shiny dude in a nice suit to tell them he can help them to "dominate" the "entire state", with results guaranteed in 3 months.
Not that I would do such a thing. But when grown men still believe in Santa Claus, the Easter Bunny AND the Tooth Fairy, they certainly deserve SOME kind of kick in the ass, to wake them up.
