Price of gas at Costco, San Marcos, CA (suburb of San Diego & 62 miles north of Tia Juana, Mexico) on 1/15/16 was $2.53 per gal, low for us. It was as low as $2.25 a month or so ago. Gas prices in CA are high because of state laws to clean up our environment (smog problems in So Cal have been greatly reduced). I think the gas companies play games with us; world prices go down and suddenly there is a crisis at a CA refinery (explosion or unscheduled maintenance) reducing the supply so they then jack the prices up... When we head out on a RV trip, we have to head east or north obviously; as soon as we enter Arizona, we fill up the tank with cheaper gas. Christmas in Florida a year ago, gas prices went downhill all the way across the US, down to $1.95 in the Tampa area! Heading for Mexico, you could by-pass most of Ca for lower prices but you will miss a lot of beautiful country. Driving the Oregon and California coast is well worth the extra cost. Jacki still has many Canadian relatives so we do feel for you Canadian friends over the exchange rate. (We already have all of our 5.0TA funds transferred to a Canadian bank!
