Actually, the US Dollar to Mexican Peso is converting the best it has since the early 1990’s. It has averaged about 10 to 1 since the mid to late 1990’s, and has gone from 9-1 this summer to better than 14-1 currently as the Mexican Peso has dropped in value about 32% from this summer.
When I was in Playa Del Carmen in late October I got 13.5 pesos to 1 US Dollar, best I have ever gotten in Mexico.
