So we're doing a one-way car rental to get us from Calgary to Jasper to start our ride. Now then, where is a convenient, safe place on the south side of Calgary (or someplace between the south side and the airport) to leave our vehicle? Or who do I contact to find that out? Alternatively, is there a good way to get two loaded tourers onto mass transit on the south side to the airport area where we'd presumably leave our car when we picked up the rental unit?
