I'm in the Valley 2 weeks out of every month and the locals are more than a joke, they're dangerous. At least in Mexico, as a norm, a $50 folded over your drivers license will be adequate to resolve most problems.
$50.00? Are you crazy? "La mordida" was only $20.00 the last time I was down there.
My how time flies. "La mordida" was only $20 last time I was in Reynosa.
