Haven't been down in a while, I hear its pretty expensive, almost 5 bucks a gallon for 91? What is the going rate? BTW the bank is giving 16.8 pesos for a dollar and the local exchange is giving 16.6. I usually get pesos before a trip because I've found you get gouged at the pump when paying in dollars but I'm not sure its less than 17 at the pump right now. BTW the current exchange rate is 18. Thanks!
