Thanks for visiting last time around but you are definitely right about gas prices. Check Gas Buddy for it will give you an idea of gas prices along the way. From PA, swing wide south of Chicago and try I39 through Wisconson. The hwy in Illinois is a little rough (at least it was last summer) but once in Wisconson it smooths out nicely. Up to Madison I90/I94 through Wisconson Dells (nice ride), I94 to Minneapolis (take southern bypass (believe it is I 494), then I 94 till you decide to turn north. National weather service is calling for huge flooding north of Fargo right to Canadian border so be careful of your route. Last time it was like this (a couple of years back) #2 was closed west of I 29 through to and past Minot ND. You might be better off staying on I 94 to Glendive Montana and then work your way up to #2 from there. Or Stay on I 29, fill at Pembina ND, take #75 to Winnipeg then #1 Trans Canada west. Right now our gas is approx $1/gal more expensive but the #1 west is in awesome condition with not much traffic to deal with (very smooth ride). The ride from Winnipeg to Calgary is about 13-14 hours so depending on your mpg it would cost you a couple hundred more to take this route. One thing to consider is that the savings in gas running across North Dakota and Montana is used up traveling the distance from the border to Calgary. Where ever you decide to cross, just make sure your tank is full. When we are touring our Province it is well worth the trip to go down to Grand Forks (on a near empty tank) spend a couple of days, do the grocery shopping, bring across some inexpensive adult beverages, and then fill the tank as much as it will take at Pembina. (though our beers are great, it'll cost you $30 or so a doz to enjoy them). Hope this was of some assistance and travel safe.
