Does anyone know where I can buy an RV Campground membership in Alberta?

Or a directory that lists all members RV campsites in Alberta. I study Wilderness Village in Alberta, but found their fees too expensive. Your help is most appreciated.

Here is a site I use, but if they find it too expensive, then go to the parks of Canada; payment of a Park & Camping go, gets you into the parks, the soil of the field and elsewhere. http://www.campcanada.com/
