FYI, gas in Why at the Why Not and Chevron was $2.59, but at the Casino it was $2.34- for a savings of $.25/gallon it's worth the one mile drive east! At the new Pemex in Sonoyta on 15th of Sept. Street it was $2.28 (7.72 pesos x 3.8 / $12.85 pesos per dollar). We didn't check out how much gas was in Penasco, but it's usually cheaper than at the border.
