Sun Peaks does this every year, the first Monday in December for Kamloops residents lift tickets are $5Cdn plus a donation to the food bank. All of the high schools close down because pretty much no one shows up for school, the one day a year crowd is out in full force, Value Village sells out all their $10 1970s skis and the ski patrol has their busiest day of the year. It is a real honest to goodness Gaper Day.
Locals call it "Body Pack the Hill Day" and of course don't go near the mountain that day.
