I just looked it up. Drumheller has camping sites, with 15-30 charging facilities. If you make it a camping trip overnight, you could get a charge enough to make it to Canmore.That sucks...was planning to take my 4 and 6 year olds to Drumheller through Calgary next summer and was hoping The Calgary SC would be in place by then. Oh well, I guess we might go on a Disney roadtrip instead.
There are adapters.
