Calling Lake is a Hamlet 2.5 hours North of Edmonton. The road it is on leads to Fort McMurray.
Note that there is a lot of traffic on this road at all times; Fort McMurray is Alberta's oil and gas producer - the bigwigs of oil and gas all have huge refineries there, and a lot of people go back and forth to the camps for work.
With that in mind, Calling Lake is a hamlet....it is very small, and people from Fort Mac would not "need to go there" to go skating.
My pondering:
1. The man/voice is someone who drives the road from Red Deer to Fort Mac (Alberta QE II highway) frequently. High traffic here - dropped the bag with ID as it was not found until early 2013.
2. The man is a truck driver or oilsands worker.
3. The man lives near Edmonton - when he says "50th street," that is a backroad area that would have taken them to Beaumont/Nisku area. This is not a main road at all, and Beaumont is not a large community.
