I'm not so sure about that, Ger.......... a few years ago hauling the 5th wheel, we were thinking of camping near Banff and missed the turnoff and wound up camping at some lake, I think it was Minny Wanker! .
Jasper is good as long as you don't have to buy anything.
We cheated, a friend worked on the rail line and lived there. Back in the day if you lived there you got a "special price" on nearly everything ;-)
