The casino in Prince Albert has free parking for RV's, and maybe four or five have electricity. All you have to do is go in and register. They have a nice restaurant in the casino. We have also overnighted at Walmarts in SK and AB. We go in and ask if we may stay and we have always been welcomed. It is disgusting sometimes to see the privilege being abused.
Whitehorse, YT Walmart is a sight to see in the summer time.
By afternoon it is full of huge 5th wheel and self-propelled RV's, 99% US plates. They are parked willy nilly all over the lot. We parked at the gov't campground. I wonder if the poor people in those land yachts maybe can't afford a commercial campsite? Frankly, I don't really care where you park, just have a bit of consideration for others.
