I thought about posting on BuyCanadian but I was worried they would find it off-topic as that place is more focused on products. (e.g. Not so a place for talking about a Canadian book you read recently.)
That's a good point about splitting it up between the different locations. EhVideos seems like it has the shows/movies/old commercials covered. MapleMusic would work if I wanted to talk about Unleash the Archers or something like that.
I'm not necessarily opposed to creating one, though.
I don't know if this holds true in general, but I noticed on a road trip that when we crossed from BC to Alberta, the rest areas seemed to disappear. Like in BC most roads have stops along the way with gravel parking lots, maybe a little park with an outhouse and a picnic table, or a viewpoint with some signs describing history. When we crossed into Alberta it was like the rest stops disappeared. But it might have just been the road we were taking.
